Which databases does Yii support?

Yii uses PDO, which is good, as it supports parameters, which can help to prevent SQL injection attacks.

As of Yii 1.1.8, it supports the following:

• PostgreSQL
• MySQL

• Microsoft SQL Server
• Oracle

Yii also supports dblib

Some other useful database features supported by Yii include:
