use Doctrine :)

Doctrine is stable, well documented and feature rich.

This project attempts to generate the most accurate SQL dialect for the targeted DBMS while Doctrine DBAL delegate this task to higher level modules such as Doctrine ORM.

Doctrine Platform interface contains a very huge number of functions, one for each thing thant may differ from one DBMS/Driver to another. This project attempts to keep a cleaner and smaller set of functions.

As in Doctrine, a column is an abstracted table column description
