how do I delete rows in Yii?

Question

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);

Solution 1

A prettier solution is

YourUserModel::model()->deleteAll("day !='" . date('Y-m-d') . "'");

Solution 2

Better user PDO parameters and on command you also have to call execute

$query = "delete from `user_login_hash` where `day`<> :date";
$command = Yii::app()->db->createCommand($query);
$command->execute(array('date' => date('Y-m-d')));

or

UserLoginHash::model()->deleteAll(
    'day <> :date',
    array('date' => date('Y-m-d'))
);

Solution 3

Try this...

 $query = "delete from `user_login_hash` where `day`!='".(date('Y-m-d',time()))."'";
                        $query->queryAll($query);

Solution 4

You may use query builder

$command = Yii::app()->db->createCommand()
    ->delete('user_login_hash', 'day !=' . date('Y-m-d'));
