controller中CDbConnection::createCommand($statussql)报错

[guoyiyuhen]

我在一个controller动作里调用下面语句，结果报错，请大家指点下原因。

$command = CDbConnection::createCommand($sql);

报错：

XXXController does not have a method named "getActive".

试试～

$command = Yii::app()->db->createCommand($sql);

createCommand 为 CDbConnection的公共静态方法，必须通过实例调用～
