Alter table or reset auto-increment using CDbMigration

问题

How can I alter table or reset the auto-increment of a field in Yii 1.x, using CDbMigration?

I found alterColumn method, as good as createTable, dropTable, renameTable and truncateTable methods, but either I'm blind or there isn't anything for altering table or resetting the auto-increment of particular column or field.

You can use execute() as Yii defines it:

Executes a SQL statement. This method executes the specified SQL statement using dbConnection.

So,

$this->execute("ALTER TABLE tbl_name AUTO_INCREMENT = 1");
