Yii deleteByAttributs 用法，慎用Dao的delete_PHP教程

MyClass::model()->deleteAllByAttributes(array(
    'phone_number'=>$phoneNumber,
));

MyClass::model()->deleteAllByAttributes(array(),'`phone_number` = :phone_number',array(
    ':phone_number'=>$phoneNumber,
));

MyClass::model()->deleteAll('`phone_number` = :phone_number',array(
    ':phone_number'=>$phoneNumber,
));

$condition = new CDbCriteria();
$condition->addCondition('status=:status');
$condition->params = array(':status'=>1);
$condition->addInCondition('user_id',array(100111,100221,100221));
User::model()->deleteAll($condition);Dao带in条件的示例

Yii::app()->db->createCommand()
->delete('mw_user', array('and', 'user_id=:user_id', array('in', 'position_id', array(1,2,3))),array(':user_id'=>121111));
