PDO driver for MySQL

This is the preferred driver for connections to the following databases:

This preferred driver uses the PHP mysqli interface and supports all table types, with full support for transactions and rollback when the table type supports it.

This driver replaces both mysql and mysqlt drivers.


Migrating To The mysqli driver

If you are still using the mysql ormysqlt drivers you should be planning on migrating to the mysqli driver. Support for both drivers is built into PHP up to version PHP 5.4. From an ADOdb standpoint, it is simply a case of switching from

$db = newAdoConnection('mysql')

to

$db = newAdoConnection('mysqli')

Driver Specific Issues

renameColumnSql

The method renameColumnSql normally takes 3 parameters, $tableName, $oldColumnName and $newColumnName. When used with the mysql provider, a full definition of the column must be provided, as if creating the column new

Usage

/*
* We are going to rename a column from col9 to col6.
*/
$flds = 'col6 C(50) NOTNULL DEFAULT "BILL"';
 
# Then create a data dictionary object, using this connection
$dict = NewDataDictionary($db);
 
$sql = $dict->renameColumnSql($table,'col9','col6', $flds);
