 Dibi automatically detects the types of query columns and converts fields them to native PHP types. We can also specify the type manually. You can find the possible types in the `Dibi\Type` class.
 
 ```php
-$result->setType('id', Dibi\Type::Integer); // id will be integer
+$result->setType('id', Dibi\Type::INTEGER); // id will be integer
 $row = $result->fetch();
 
 is_int($row->id) // true
