Yii：以最高平均評分爲基礎獲取數據

Question

我是一個可愛的人，我想從我的「NgoRateReviewNgo」表中獲得前5名。前5名Ngo的條件是，它應該首先找到Ngo的平均評分，然後顯示那些平均評分最高的5個Ngo。這是我的查看文件的代碼，幷包含SQL查詢

請幫我這個。

這應該是查詢

$user=UserRateReviewNgo::model()->findAll(array(
    'condition' => 'YEAR(date_created)=:year and MONTH(date_created)=:month', 
    'params' => array(':year'=>2016, ':month'=>$month), 
    'select'=>'avg(rate),ngo_id', 
    'group' => 'ngo_id', 
'order'=>'rate DESC', 
'limit' => 5 
));
