Latest version of ADODB is available at http://php.weblogs.com/adodb
======================================================================
This file provides PHP4 session management using the ADODB database
wrapper library.
Example
=======
GLOBAL $HTTP_SESSION_VARS;
include('adodb.inc.php');
include('adodb-session.php');
session_start();
session_register('AVAR');
$HTTP_SESSION_VARS['AVAR'] += 1;
print "<p>\$HTTP_SESSION_VARS['AVAR']={$HTTP_SESSION_VARS['AVAR']}</p>";
Installation
============
1. Create a new database in MySQL or Access "sessions" like
so:
create table sessions (
SESSKEY char(32) not null,
EXPIRY int(11) unsigned not null,
DATA text not null,
primary key (sesskey)
);
2. Then define the following parameters in this file:
$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
$ADODB_SESSION_CONNECT='server to connect to';
$ADODB_SESSION_USER ='user';
$ADODB_SESSION_PWD ='password';
$ADODB_SESSION_DB ='database';
$ADODB_SESSION_TBL = 'sessions'
3. Recommended is PHP 4.0.2 or later. There are documented
session bugs in
earlier versions of PHP.

Latest version of ADODB is available at http://php.weblogs.com/adodb
======================================================================
This file provides PHP4 session management using the ADODB database
wrapper library.
Example
=======
GLOBAL $HTTP_SESSION_VARS;
include('adodb.inc.php');
include('adodb-session.php');
session_start();
session_register('AVAR');
$HTTP_SESSION_VARS['AVAR'] += 1;
print "<p>\$HTTP_SESSION_VARS['AVAR']={$HTTP_SESSION_VARS['AVAR']}</p>";
Installation
============
1. Create a new database in MySQL or Access "sessions" like
so:
create table sessions (
SESSKEY char(32) not null,
EXPIRY int(11) unsigned not null,
DATA text not null,
primary key (sesskey)
);
2. Then define the following parameters in this file:
$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
$ADODB_SESSION_CONNECT='server to connect to';
$ADODB_SESSION_USER ='user';
$ADODB_SESSION_PWD ='password';
$ADODB_SESSION_DB ='database';
$ADODB_SESSION_TBL = 'sessions'
3. Recommended is PHP 4.0.2 or later. There are documented
session bugs in
earlier versions of PHP.

Cursortype when calling odbc_pconnect(....).
And the exciting thing: When we set the cursor type
to SQL_CUR_USE_ODBC Cursor Type, then
the whole query speed up from 1 till 10 seconds
to 0.2 till 0.3 seconds for 100 records. Amazing!!!
Therfore, PHP is just almost fast as calling the DB2
from Servlets using JDBC (don't take too much care
about the speed at whole: the database was on a
completely other location, so the whole connection
was made over a slow network connection).
I hope this helps when other encounter the same
problem when trying to connect to DB2 from
PHP.
Kind regards,
Christian Szardenings
2 Oct 2001
Mark Newnham has discovered that the SQL_CUR_USE_ODBC is not supported by
IBM's DB2 ODBC driver, so this must be a 3rd party ODBC driver.
From the IBM CLI Reference:
SQL_ATTR_ODBC_CURSORS (DB2 CLI v5)
This connection attribute is defined by ODBC, but is not supported by DB2
CLI. Any attempt to set or get this attribute will result in an SQLSTATE of
HYC00 (Driver not capable).
A 32-bit option specifying how the Driver Manager uses the ODBC cursor
library.
So I guess this means the message [above] was related to using a 3rd party
odbc driver.

/*
NLS_Date_Format
Allows you to use a date format other than the Oracle Lite default. When a literal
character string appears where a date value is expected, the Oracle Lite database
tests the string to see if it matches the formats of Oracle, SQL-92, or the value
specified for this parameter in the POLITE.INI file. Setting this parameter also
defines the default format used in the TO_CHAR or TO_DATE functions when no
other format string is supplied.
For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is
yy-mm-dd or yyyy-mm-dd.
Using 'RR' in the format forces two-digit years less than or equal to 49 to be
interpreted as years in the 21st century (2000–2049), and years over 50 as years in
the 20th century (1950–1999). Setting the RR format as the default for all two-digit
year entries allows you to become year-2000 compliant. For example:
NLS_DATE_FORMAT='RR-MM-DD'
You can also modify the date format using the ALTER SESSION command.

Time 0.6081s (1644.60 inserts/sec) with direct OCIParse/OCIExecute
Time 0.6341s (1577.16 inserts/sec) with ADOdb Prepare/Bind/Execute
Time 1.5533s ( 643.77 inserts/sec) with pure SQL using Execute
Now if PHP only had batch/bulk updating like Java or PL/SQL...
Note that the order of parameters differs from OCIBindByName,

21.02.2002 - Wade Johnson wade@wadejohnson.de
Extended ODBC class for Sybase SQLAnywhere.
1) Added support to retrieve the last row insert ID on tables with
primary key column using autoincrement function.
2) Added blob support. Usage:
a) create blob variable on db server:
$dbconn->create_blobvar($blobVarName);
b) load blob var from file. $filename must be complete path
$dbcon->load_blobvar_from_file($blobVarName, $filename);
c) Use the $blobVarName in SQL insert or update statement in the values
clause:
$recordSet = $dbconn->Execute('INSERT INTO tabname (idcol, blobcol) '
.
'VALUES (\'test\', ' . $blobVarName . ')');
instead of loading blob from a file, you can also load from
an unformatted (raw) blob variable:
$dbcon->load_blobvar_from_var($blobVarName, $varName);
d) drop blob variable on db server to free up resources:
$dbconn->drop_blobvar($blobVarName);
Sybase_SQLAnywhere data driver. Requires ODBC.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library.
We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library.
In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place.
e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

>> ADODB Library for PHP4
(c) 2000-2002 John Lim (jlim@natsoft.com.my)
Released under both BSD and GNU Lesser GPL library license.
This means you can use it in proprietary products.
>> Introduction
PHP's database access functions are not standardised. This creates a
need for a database class library to hide the differences between the
different databases (encapsulate the differences) so we can easily
switch databases.
We currently support MySQL, Interbase, Sybase, PostgreSQL, Oracle,
Microsoft SQL server, Foxpro ODBC, Access ODBC, Informix, DB2 ODBC,
Sybase SQL Anywhere, generic ODBC and Microsoft's ADO.
We hope more people will contribute drivers to support other databases.
>> Documentation and Examples
Refer to readme.htm for full documentation and examples. There is also a
tutorial tute.htm that contrasts ADODB code with mysql code.
>>> Files
Adodb.inc.php is the main file. You need to include only this file.
Adodb-*.inc.php are the database specific driver code.
Test.php contains a list of test commands to exercise the class library.
Adodb-session.php is the PHP4 session handling code.
Testdatabases.inc.php contains the list of databases to apply the tests on.
Benchmark.php is a simple benchmark to test the throughput of a simple SELECT
statement for databases described in testdatabases.inc.php. The benchmark
tables are created in test.php.
readme.htm is the main documentation.
tute.htm is the tutorial.

<title>Tips on Writing Portable SQL for Multiple Databases for PHP</title>
</head>
<body bgcolor=white>
<table width=100% border=0><tr><td><h2>Tips on Writing Portable SQL &nbsp;</h2></td><td>
<div align=right><img src="cute_icons_for_site/adodb.gif"></div></td></tr></table>
If you are writing an application that is used in multiple environments and
operating systems, you need to plan to support multiple databases. This article
is based on my experiences with multiple database systems, stretching from 4th
Dimension in my Mac days, to the databases I currently use, which are: Oracle,
FoxPro, Access, MS SQL Server and MySQL. Although most of the advice here applies
to using SQL with Perl, Python and other programming languages, I will focus on PHP and how
the <a href="http://php.weblogs.com/adodb">ADOdb</a> database abstraction library
offers some solutions.<p></p>
<p>Most database vendors practice product lock-in. The best or fastest way to
do things is often implemented using proprietary extensions to SQL. This makes
it extremely hard to write portable SQL code that performs well under all conditions.
When the first ANSI committee got together in 1984 to standardize SQL, the database
vendors had such different implementations that they could only agree on the
core functionality of SQL. Many important application specific requirements
were not standardized, and after so many years since the ANSI effort began,
it looks as if much useful database functionality will never be standardized.
Even though ANSI-92 SQL has codified much more, we still have to implement portability
at the application level.</p>
<h3><b>Selects</b></h3>
<p>The SELECT statement has been standardized to a great degree. Nearly every
database supports the following:</p>
<p>SELECT [cols] FROM [tables]<br>
&nbsp;&nbsp;[WHERE conditions]<br>
&nbsp; [GROUP BY cols]<br>
&nbsp; [HAVING conditions] <br>
&nbsp; [ORDER BY cols]</p>
<p>But so many useful techniques can only be implemented by using proprietary
extensions. For example, when writing SQL to retrieve the first 10 rows for
paging, you could write...</p>
<table width="80%" border="1" cellspacing="0" cellpadding="0" align="center">
<tr>
<td><b>Database</b></td>
<td><b>SQL Syntax</b></td>
</tr>
<tr>
<td>DB2</td>
<td>select * from table fetch first 10 rows only</td>
</tr>
<tr>
<td>Informix</td>
<td>select first 10 * from table</td>
</tr>
<tr>
<td>Microsoft SQL Server and Access</td>
<td>select top 10 * from table</td>
</tr>
<tr>
<td>MySQL and PostgreSQL</td>
<td>select * from table limit 10</td>
</tr>
<tr>
<td>Oracle</td>
<td>select * from (select * from table) where rownum &lt;= 10</td>
</tr>
</table>
<p>This feature of getting a subset of data is so useful that in the PHP class
library ADOdb, we have a SelectLimit( ) function that allows you to hide the
implementation details within a function that will rewrite your SQL for you:</p>
<pre>$connection-&gt;SelectLimit('select * from table', 10);
</pre>
<p><b>Selects: Fetch Modes</b></p>
<p>PHP allows you to retrieve database records as arrays. You can choose to have
the arrays indexed by field name or number. However different low-level PHP
database drivers are inconsistent in their indexing efforts. ADOdb allows you
to determine your prefered mode. You set this by setting the variable $ADODB_FETCH_MODE
to either of the constants ADODB_FETCH_NUM (for numeric indexes) or ADODB_FETCH_ASSOC
(using field names as an associative index).</p>
<p>The default behaviour of ADOdb varies depending on the database you are using.
For consistency, set the fetch mode to either ADODB_FETCH_NUM (for speed) or
ADODB_FETCH_ASSOC (for convenience) at the beginning of your code. </p>
<p><b>Selects: Counting Records</b></p>
<p>Another problem with SELECTs is that some databases do not return the number
of rows retrieved from a select statement. This is because the highest performance
databases will return records to you even before the last record has been found.
</p>
<p>In ADOdb, RecordCount( ) returns the number of rows returned, or will emulate
it by buffering the rows and returning the count after all rows have been returned.
This can be disabled for performance reasons when retrieving large recordsets
by setting the global variable $ADODB_COUNTRECS = false. This variable is checked
every time a query is executed, so you can selectively choose which recordsets
to count.</p>
<p>If you prefer to set $ADODB_COUNTRECS = false, ADOdb still has the PO_RecordCount(
) function. This will return the number of rows, or if it is not found, it will
return an estimate using SELECT COUNT(*):</p>
<pre>$rs = $db-&gt;Execute(&quot;select * from table where state=$state&quot;);
$numrows = $rs-&gt;PO_RecordCount('table', &quot;state=$state&quot;);</pre>
<p><b>Selects: Locking</b> </p>
<p>SELECT statements are commonly used to implement row-level locking of tables.
Other databases such as Oracle, Interbase, PostgreSQL and MySQL with InnoDB
do not require row-level locking because they use versioning to display data
consistent with a specific point in time.</p>
<p>Currently, I recommend encapsulating the row-level locking in a separate function,
such as RowLock($table, $where):</p>
<pre>$connection-&gt;BeginTrans( );
$connection-&gt;RowLock($table, $where); </pre>
<pre><font color=green># some operation</font></pre>
<pre>if ($ok) $connection-&gt;CommitTrans( );
else $connection-&gt;RollbackTrans( );
</pre>
<p><b>Selects: Outer Joins</b></p>
<p>Not all databases support outer joins. Furthermore the syntax for outer joins
differs dramatically between database vendors. One portable (and possibly slower)
method of implementing outer joins is using UNION.</p>
<p>In Microsoft SQL Server a left outer join between two tables t1 and t2 could
look like:</p>
<pre>SELECT t1.col1, t1.col2, t2.cola <br> FROM t1 LEFT JOIN t2 ON t1.col = t2.col</pre>
<p>This can be emulated using:</p>
<pre>SELECT t1.col1, t1.col2, t2.cola FROM t1, t2 <br> WHERE t1.col = t2.col
UNION ALL
SELECT col1, col2, null FROM t1 <br> WHERE t1.col not in (select distinct col from t2)</pre>
<h3><b>Inserts</b> </h3>
<p>When you create records, you need to generate unique id's for each record.
There are two common techniques: (1) auto-incrementing columns and (2) sequences.
</p>
<p>Auto-incrementing columns are supported by MySQL, Sybase and Microsoft Access
and SQL Server. However most other databases do not support this feature. So
for portability, you have little choice but to use sequences. Sequences are
special functions that return a unique incrementing number every time you call
it, suitable to be used as database keys. In ADOdb, we use the GenID( ) function.
It has takes a parameter, the sequence name. Different tables can have different
sequences. </p>
<pre>$id = $connection-&gt;GenID('sequence_name');<br>$connection-&gt;Execute(&quot;insert into table (id, firstname, lastname) <br> values ($id, $firstname, $lastname)&quot;);</pre>
<p>For databases that do not support sequences natively, ADOdb emulates sequences
by creating a table for every sequence.</p>
<h3><b>Binding</b></h3>
<p>Binding variables in an SQL statement is another tricky feature. Binding is
useful because it allows pre-compilation of SQL. When inserting multiple records
into a database in a loop, binding can offer a 50% (or greater) speedup. However
many databases such as Access and MySQL do not support binding natively and
there is some overhead in emulating binding. Furthermore, different databases
(specificly Oracle!) implement binding differently. My recommendation is to
use binding if your database queries are too slow, but make sure you are using
a database that supports it like Oracle. </p>
<p>ADOdb supports portable Prepare/Execute with:</p>
<pre>$stmt = $db-&gt;Prepare('select * from customers where custid=? and state=?');
$rs = $db-&gt;Execute($stmt, array($id,'New York'));</pre>
<h2>DDL</h2>
<p>There are database design tools such as ERWin or Dezign that allow you to generate
data definition language commands such as ALTER TABLE or CREATE INDEX from Entity-Relationship
diagrams. Other developers such as Manuel Lemos have developed portable XML
based schemas for PHP with Metabase. I think this might suit many developers,
but I prefer to manually define the database tables. This is because the placement
of tables and selection of the different types of indexes has to be planned
based on the number of hard disks and the i/o characteristics of the data. This
can only be done manually. Here are some tuning hints:</p>
<ul>
<li>The most important and frequently used tables deserve to be placed on their
own separate hard disks. </li>
<li>Indexes and data should be kept on different hard disks. </li>
<li>Transaction logs and rollback segments deserve their own hard disks.</li>
<li>Be prepared to waste space. You probably need at least 5 hard disks for
a high-performance database system:<br>
- 1 hard disk for the operating system and temporary data, <br>
- 1 for data,<br>
- 1 for indexes, <br>
- 1 for rollback, <br>
- 1 for transaction logs.</li>
</ul>
<h3>Data Types</h3>
<p>Stick to a few data types that are available in most databases. Char, varchar
and numeric/number are supported by most databases. Most other data types (including
integer, boolean and float) cannot be relied on being available. I recommend
using char(1) or number(1) to hold booleans. </p>
<p>Different databases have different ways of representing dates and timestamps/datetime.
ADOdb attempts to display all dates in ISO (YYYY-MM-DD) format. ADOdb also provides
DBDate( ) and DBTimeStamp( ) to convert dates to formats that are acceptable
to that database. Both functions accept Unix integer timestamps and date strings
in ISO format.</p>
<pre>$date1 = $connection-&gt;DBDate(time( ));<br>$date2 = $connection-&gt;DBTimeStamp('2002-02-23 13:03:33');</pre>
<p>We also provide functions to convert database dates to Unix timestamps:</p>
<pre>$unixts = $recordset-&gt;UnixDate('#2002-02-30#'); <font color="green"># MS Access date =&gt; unix timestamp</font></pre>
<p>The maximum length of a char/varchar field is also database specific. You can
only assume that field lengths of up to 250 characters are supported. This is
normally impractical for web based forum or content management systems. You
will need to be familiar with how databases handle large objects (LOBs). ADOdb
implements two functions, UpdateBlob( ) and UpdateClob( ) that allow you to
update fields holding Binary Large Objects (eg. pictures) and Character Large
Objects (eg. HTML articles):</p>
<pre><font color=green># for oracle </font>
$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1,empty_blob())');
$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
<font color=green># non-oracle databases</font>
$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)');
$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
</pre>
<p>Null handling is another area where differences can occur. In general, I avoid
using nulls except for dates and default all my numeric and character fields
to 0 or the empty string. This maintains consistency with PHP, where empty strings
and zero are treated as equivalent. However if your database has significant
amounts of missing or unknown data, using nulls might be a good idea.
<h3><b>Stored Procedures</b></h3>
<p>Stored procedures are another problem area. Some databases allow recordsets
to be returned in a stored procedure (Microsoft SQL Server and Sybase), and
others only allow output parameters to be returned. Stored procedures sometimes
need to be wrapped in special syntax. For example, Oracle requires such code
to be wrapped in an anonymous block with BEGIN and END. Also internal sql functions
such as +, ||, TRIM( ), SUBSTR( ) or INSTR( ) vary between vendors. </p>
<p>An example of how to call a stored procedure with 2 parameters and 1 return
value follows:</p>
<pre> switch ($db->databaseType) {
case '<font color="#993300">mssql</font>':
$sql = <font color="#000000"><font color="#993333">'<font color="#993300">SP_RUNSOMETHING</font>'</font></font>; break;
case '<font color="#993300">oci8</font>':
$sql =
<font color="#993300"> </font><font color="#000000"><font color="#993300">&quot;declare RETVAL integer;begin :RETVAL := </font><font color="#000000"><font color="#993333"><font color="#993300">SP_RUNSOMETHING</font></font></font><font color="#993300">(:myid,:group);end;&quot;;
</font> break;</font>
default:
die('<font color="#993300">Unsupported feature</font>');
}
<font color="#000000"><font color="green"> # @RETVAL = SP_RUNSOMETHING @myid,@group</font>
$stmt = $db-&gt;PrepareSP($sql); <br> $db-&gt;Parameter($stmt,$id,'<font color="#993300">myid</font>');
$db-&gt;Parameter($stmt,$group,'<font color="#993300">group</font>');
<font color="green"># true indicates output parameter<br> </font>$db-&gt;Parameter($stmt,$ret,'<font color="#993300">RETVAL</font>',true);
$db-&gt;Execute($stmt); </font></pre>
<p>As you can see, the ADOdb API is the same for both databases. But the stored
procedure SQL syntax is quite different between databases and is not portable,
so be forewarned! However sometimes you have little choice as some systems only
allow data to be accessed via stored procedures. This is when the ultimate portability
solution might be the only solution: <i>treating portable SQL as a localization
exercise...</i></p>
<h3><b>SQL as a Localization Exercise</b></h3>
<p> In general to provide real portability, you will have to treat SQL coding
as a localization exercise. In PHP, it has become common to define separate
language files for English, Russian, Korean, etc. Similarly, I would suggest
you have separate Sybase, Intebase, MySQL, etc files, and conditionally include
the SQL based on the database. For example, each MySQL SQL statement would be
stored in a separate variable, in a file called 'mysql-lang.inc.php'.</p>
<pre>$sqlGetPassword = '<font color="#993300">select password from users where userid=%s</font>';
$sqlSearchKeyword = &quot;<font color="#993300">SELECT * FROM articles WHERE match (title,body) against (%s</font>)&quot;;</pre>
<p>In our main PHP file:</p>
<pre><font color=green># define which database to load...</font>
<b>$database = '<font color="#993300">mysql</font>';
include_once(&quot;<font color="#993300">$database-lang.inc.php</font>&quot;);</b>
$db = NewADOConnection($database);
$db->PConnect(...) or die('<font color="#993300">Failed to connect to database</font>');
<font color=green># search for a keyword $word</font>
$rs = $db-&gt;Execute(sprintf($sqlSearchKeyWord,$db-&gt;qstr($word)));</pre>
<p>Note that we quote the $word variable using the qstr( ) function. This is because
each database quotes strings using different conventions.</p>
<p>
<h3>Final Thoughts</h3>
<p>The best way to ensure that you have portable SQL is to have your data tables designed using
sound principles. Learn the theory of normalization and entity-relationship diagrams and model
your data carefully. Understand how joins and indexes work and how they are used to tune performance.

<h1>Tutorial: Moving from MySQL to ADODB</h1>
<pre> You say eether and I say eyether,
You say neether and I say nyther;
Eether, eyether, neether, nyther -
Let's call the whole thing off !
<br>
You like potato and I like po-tah-to,
You like tomato and I like to-mah-to;
Potato, po-tah-to, tomato, to-mah-to -
Let's call the whole thing off !
</pre>
<p>I love this song, especially the version with Louis Armstrong and Ella singing
duet. It is all about how hard it is for two people in love to be compatible
with each other. It's about compromise and finding a common ground, and that's
what this article is all about.
<p>PHP is all about creating dynamic web-sites with the least fuss and the most
fun. To create these websites we need to use databases to retrieve login information,
to splash dynamic news onto the web page and store forum postings. So let's
say we were using the popular MySQL database for this. Your company has done
such a fantastic job that the Web site is more popular than your wildest dreams.
You find that MySQL cannot scale to handle the workload; time to switch databases.
<p> Unfortunately in PHP every database is accessed slightly differently. To connect
to MySQL, you would use <i>mysql_connect()</i>; when you decide to upgrade to
Oracle or Microsoft SQL Server, you would use <i>ocilogon() </i>or <i>mssql_connect()</i>
respectively. What is worse is that the parameters you use for the different
connect functions are different also.. One database says po-tato, the other
database says pota-to. Oh-oh.
<h3>Let's NOT call the whole thing off</h3>
<p>A database wrapper library such as ADODB comes in handy when you need to ensure portability. It provides
you with a common API to communicate with any supported database so you don't have to call things off. <p>
<p>ADODB stands for Active Data Objects DataBase (sorry computer guys are sometimes
not very original). ADODB currently supports MySQL, PostgreSQL, Oracle, Interbase,
Microsoft SQL Server, Access, FoxPro, Sybase, ODBC and ADO. You can download
ADODB from <a href=http://php.weblogs.com/adodb><a href="http://php.weblogs.com/adodb">http://php.weblogs.com/adodb</a></a>.
<h3>MySQL Example</h3>
<p>The most common database used with PHP is MySQL, so I guess you should be familiar
with the following code. It connects to a MySQL server at <i>localhost</i>,
database <i>mydb</i>, and executes an SQL select statement. The results are
printed, one line per row.
<pre><font color="#666600">$db = <b>mysql_connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;);
<b>mysql_select_db</b>(&quot;mydb&quot;,$db);</font>
<font color="#660000">$result = <b>mysql_query</b>(&quot;SELECT * FROM employees&quot;,$db)</font><code><font color="#663300">;
if ($result === false) die(&quot;failed&quot;);</font></code>
<font color="#006666"><b>while</b> ($fields =<b> mysql_fetch_row</b>($result)) &#123;
<b>for</b> ($i=0, $max=sizeof($fields); $i &lt; $max; $i++) &#123;
<b>print</b> $fields[$i].' ';
&#125;
<b>print</b> &quot;&lt;br&gt;\n&quot;;
&#125;</font>
</pre>
<p>The above code has been color-coded by section. The first section is the connection
phase. The second is the execution of the SQL, and the last section is displaying
the fields. The <i>while</i> loop scans the rows of the result, while the <i>for</i>
loop scans the fields in one row.</p>
<p>Here is the equivalent code in ADODB</p>
<pre><b><font color="#666600"> include(&quot;adodb.inc.php&quot;);</b>
$db = <b>NewADOConnection</b>('mysql');
$db-&gt;<b>Connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;, &quot;mydb&quot;);</font>
<font color="#663300">$result = $db-&gt;<b>Execute</b>(&quot;SELECT * FROM employees&quot;);
</font><font color="#663300"></font><code><font color="#663300">if ($result === false) die(&quot;failed&quot;)</font></code><code><font color="#663300">;</font></code>
<font color="#006666"><b>while</b> (!$result-&gt;EOF) &#123;
<b>for</b> ($i=0, $max=$result-&gt;<b>FieldCount</b>(); $i &lt; $max; $i++)
<b>print</b> $result-&gt;fields[$i].' ';
$result-&gt;<b>MoveNext</b>();
<b>print</b> &quot;&lt;br&gt;\n&quot;;
&#125;</font> </pre>
<p></p>
<p>Now porting to Oracle is as simple as changing the second line to <code>NewADOConnection('oracle')</code>.
Let's walk through the code...</p>
<h3>Connecting to the Database</h3>
<p></p>
<pre><b><font color="#666600">include(&quot;adodb.inc.php&quot;);</b>
$db = <b>NewADOConnection</b>('mysql');
$db-&gt;<b>Connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;, &quot;mydb&quot;);</font></pre>
<p>The connection code is a bit more sophisticated than MySQL's because our needs
are more sophisticated. In ADODB, we use an object-oriented approach to managing
the complexity of handling multiple databases. We have different classes to
handle different databases. If you aren't familiar with object-oriented programing,
don't worry -- the complexity is all hidden away in the<code> NewADOConnection()</code>
function.</p>
<p>To conserve memory, we only load the PHP code specific to the database you
are connecting to. We do this by calling <code>NewADOConnection(databasedriver)</code>.
Legal database drivers include <i>mysql, mssql, oracle, oci8, postgres, sybase,
vfp, access, ibase </i>and many others.</p>
<p>Then we create a new instance of the connection class by calling <code>NewADOConnection()</code>.
Finally we connect to the database using <code>$db-&gt;Connect(). </code></p>
<h3>Executing the SQL</h3>
<p><code><font color="#663300">$result = $db-&gt;<b>Execute</b>(&quot;SELECT *
FROM employees&quot;);<br>
if ($result === false) die(&quot;failed&quot;)</font></code><code><font color="#663300">;</font></code>
<br>
</p>
<p>Sending the SQL statement to the server is straight forward. Execute() will
return a recordset object on successful execution. You should check $result
as we do above.
<p>An issue that confuses beginners is the fact that we have two types of objects
in ADODB, the connection object and the recordset object. When do we use each?
<p>The connection object ($db) is responsible for connecting to the database,
formatting your SQL and querying the database server. The recordset object ($result)
is responsible for retrieving the results and formatting the reply as text or
as an array.
<p>The only thing I need to add is that ADODB provides several helper functions
for making INSERT and UPDATE statements easier, which we will cover in the Advanced
section.
<h3>Retrieving the Data<br>
</h3>
<pre><font color="#006666"><b>while</b> (!$result-&gt;EOF) &#123;
<b>for</b> ($i=0, $max=$result-&gt;<b>FieldCount</b>(); $i &lt; $max; $i++)
<b>print</b> $result-&gt;fields[$i].' ';
$result-&gt;<b>MoveNext</b>();
<b>print</b> &quot;&lt;br&gt;\n&quot;;
&#125;</font></pre>
<p>The paradigm for getting the data is that it's like reading a file. For every
line, we check first whether we have reached the end-of-file (EOF). While not
end-of-file, loop through each field in the row. Then move to the next line
(MoveNext) and repeat.
<p>The <code>$result-&gt;fields[]</code> array is generated by the PHP database
extension. Some database extensions do not index the array by field name.
To force indexing by name - that is associative arrays -
use the $ADODB_FETCH_MODE global variable.
<pre>
$<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_NUM;
$rs1 = $db->Execute('select * from table');
$<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_ASSOC;
$rs2 = $db->Execute('select * from table');
print_r($rs1->fields); // shows <i>array([0]=>'v0',[1] =>'v1')</i>
print_r($rs2->fields); // shows <i>array(['col1']=>'v0',['col2'] =>'v1')</i>
</pre>
<p>
As you can see in the above example, both recordsets store and use different fetch modes
based on the $ADODB_FETCH_MODE setting when the recordset was created by Execute().</p>
<h2>ADOConnection<a name="ADOConnection"></a></h2>
<p>Object that performs the connection to the database, executes SQL statements
and has a set of utility functions for standardising the format of SQL statements
for issues such as concatenation and date formats.</p>
<h3>Other Useful Functions</h3>
<p><code>$recordset-&gt;Move($pos)</code> scrolls to that particular row. ADODB supports forward
scrolling for all databases. Some databases will not support backwards scrolling.
This is normally not a problem as you can always cache records to simulate backwards
scrolling.
<p><code>$recordset-&gt;RecordCount()</code> returns the number of records accessed by the
SQL statement. Some databases will return -1 because it is not supported.
<p><code>$recordset-&gt;GetArray()</code> returns the result as an array.
<p><code>rs2html($recordset)</code> is a function that is generates a HTML table based on the
$recordset passed to it. An example with the relevant lines in bold:
<pre> include('adodb.inc.php');
<b>include('tohtml.inc.php');</b> /* includes the rs2html function */
$conn = &amp;ADONewConnection('mysql');
$conn-&gt;PConnect('localhost','userid','password','database');
$rs = $conn-&gt;Execute('select * from table');
<b> rs2html($rs)</b>; /* recordset to html table */ </pre>
<p>There are many other helper functions that are listed in the documentation available at <a href="http://php.weblogs.com/adodb_manual"><a href="http://php.weblogs.com/adodb_manual">http://php.weblogs.com/adodb_manual</a></a>.
<h2>Advanced Material</h2>
<h3>Inserts and Updates </h3>
<p>Let's say you want to insert the following data into a database.
<p><b>ID</b> = 3<br>
<b>TheDate</b>=mktime(0,0,0,8,31,2001) /* 31st August 2001 */<br>
<b>Note</b>= sugar why don't we call it off
<p>When you move to another database, your insert might no longer work.</p>
<p>The first problem is that each database has a different default date format.
MySQL expects YYYY-MM-DD format, while other databases have different defaults.
ADODB has a function called DBDate() that addresses this issue by converting
converting the date to the correct format.</p>
<p>The next problem is that the <b>don't</b> in the Note needs to be quoted. In
MySQL, we use <b>don\'t</b> but in some other databases (Sybase, Access, Microsoft
SQL Server) we use <b>don''t. </b>The qstr() function addresses this issue.</p>
<p>So how do we use the functions? Like this:</p>
<pre>$sql = &quot;INSERT INTO table (id, thedate,note) values (&quot;
. $<b>ID</b> . ','
. $db-&gt;DBDate($<b>TheDate</b>) .','
. $db-&gt;qstr($<b>Note</b>).&quot;)&quot;;
$db-&gt;Execute($sql);</pre>
<p>ADODB also supports <code>$connection-&gt;Affected_Rows()</code> (returns the
number of rows affected by last update or delete) and <code>$recordset-&gt;Insert_ID()</code>
(returns last autoincrement number generated by an insert statement). Be forewarned
that not all databases support the two functions.<br>
</p>
<h3>MetaTypes</h3>
<p>You can find out more information about each of the fields (I use the words
fields and columns interchangebly) you are selecting by calling the recordset
method <code>FetchField($fieldoffset)</code>. This will return an object with
3 properties: name, type and max_length.
<pre>For example:</pre>
<pre>$recordset = $conn-&gt;Execute(&quot;select adate from table&quot;);<br>$f0 = $recordset-&gt;FetchField(0);
</pre>
<p>Then <code>$f0-&gt;name</code> will hold <i>'adata'</i>, <code>$f0-&gt;type</code>
will be set to '<i>date'</i>. If the max_length is unknown, it will be set to
-1.
<p>One problem with handling different databases is that each database often calls
the same type by a different name. For example a <i>timestamp</i> type is called
<i>datetime</i> in one database and <i>time</i> in another. So ADODB has a special
<code>MetaType($type, $max_length)</code> function that standardises the types
to the following:
<p>C: character and varchar types<br>
X: text or long character (eg. more than 255 bytes wide).<br>
B: blob or binary image<br>
D: date<br>
T: timestamp<br>
L: logical (boolean)<br>
I: integer<br>
N: numeric (float, double, money)
<p>In the above date example,
<p><code>$recordset = $conn-&gt;Execute(&quot;select adate from table&quot;);<br>
$f0 = $recordset-&gt;FetchField(0);<br>
$type = $recordset-&gt;MetaType($f0-&gt;type, $f0-&gt;max_length);<br>
print $type; /* should print 'D'</code> */
<p>
<p><b>Select Limit and Top Support</b>
<p>ADODB has a function called $connection->SelectLimit($sql,$nrows,$offset) that allows
you to retrieve a subset of the recordset. This will take advantage of native
SELECT TOP on Microsoft products and SELECT ... LIMIT with PostgreSQL and MySQL, and
emulated if the database does not support it.
<p><b>Caching Support</b>
<p>ADODB allows you to cache recordsets in your file system, and only requery the database
server after a certain timeout period with $connection->CacheExecute($secs2cache,$sql) and
$connection->CacheSelectLimit($secs2cache,$sql,$nrows,$offset).
<p><b>PHP4 Session Handler Support</b>
<p>ADODB also supports PHP4 session handlers. You can store your session variables
in a database for true scalability using ADODB. For further information, visit
<a href="http://php.weblogs.com/adodb-sessions"><a href="http://php.weblogs.com/adodb-sessions">http://php.weblogs.com/adodb-sessions</a></a>
<h3>Commercial Use Encouraged</h3>
<p>If you plan to write commercial PHP applications that you want to resell, you should consider ADODB. It has been released using the lesser GPL, which means you can legally include it in commercial applications, while keeping your code proprietary. Commercial use of ADODB is strongly encouraged! We are using it internally for this reason.<p>

<i>let's call the whole thing off</i>.<br>
<br>
<pre>
Refrain
<br>
You say eether and I say eyether,
You say neether and I say nyther;
Eether, eyether, neether, nyther -
Let's call the whole thing off !
<br>
You like potato and I like po-tah-to,
You like tomato and I like to-mah-to;
Potato, po-tah-to, tomato, to-mah-to -
Let's call the whole thing off !
<br>
But oh, if we call the whole thing off, then we must part.
And oh, if we ever part, then that might break my heart.
<br>
So, if you like pajamas and I like pa-jah-mas,
I'll wear pajamas and give up pa-jah-mas.
For we know we
Need each other, so we
Better call the calling off off.
Let's call the whole thing off !
<br>
Second Refrain
<br>
You say laughter and I say lawfter,
You say after and I say awfter;
Laughter, lawfter, after, awfter -
Let's call the whole thing off !
<br>
You like vanilla and I like vanella,
You, sa's'parilla and I sa's'parella;
Vanilla, vanella, choc'late, strawb'ry -
Let's call the whole thing off !
<br>
But oh, if we call the whole thing off, then we must part.
And oh, if we ever part, then that might break my heart.
<br>
So, if you go for oysters and I go for ersters,
I'll order oysters and cancel the ersters.
For we know we
Need each other, so we
Better call the calling off off.
Let's call the whole thing off !
