Using Yii, I want to delete all the rows that are not from today.
Is my solution ok ?
$query = "delete from `user_login_hash` where `day`!='".(date('Y-m-d',time()))."'";
Yii::app()->db->createCommand($query);
A prettier solution is
YourUserModel::model()->deleteAll("day !='" . date('Y-m-d') . "'");
