Yii Query Builder multiple where clauses

问题

I noticed in my stack that my query wasn't being executed correctly as I had multiple where clauses in my querybuilder. So I looked at this post Multiple call where in Yii Query builder

Applied what i'd read, but still the query doesn't combine the where statements. What am I doing wrong?

            $command = Yii::app()->db->createCommand()
        ....
        ->where(array('in', 'u.id', $licenses), array('and', 'i.date_added > DATE_SUB(u.date_expired, INTERVAL  30 DAY)'));
        //->where(array('and', 'i.date_added > DATE_SUB(u.date_expired, INTERVAL  30 DAY)'));
        //->where(array('and', 'u.date_expired > CURDATE()'))
        ->group('u.id');

These were 3 individual statements, but I combined them as I read, but still the same result. Only 1 where clause.

You should use andWhere method. This method is putting the AND keyword so you juste need the condition:

$command = Yii::app()->db->createCommand()
    ....
    ->where(array('in', 'u.id', $licenses));
    ->andWhere('i.date_added > DATE_SUB(u.date_expired, INTERVAL  30 DAY)');
    ->andWhere('u.date_expired > CURDATE()')
    ->group('u.id');
