Yii：在最高平均評分的基礎上獲取數據

Question

我是yiibie，我想從我的“ NgoRateReviewNgo”表中獲得前5名的ngo。 排名前5位的Ngo的條件是，它首先應該找到該Ngo的平均評分，然后才顯示平均評分最高的那5個Ngo。 這是我的視圖文件的代碼，其中包含SQL查詢

  <div class="main">
    <div class="banner">

        $monthName = $dateObj->format('F');

請幫我解決一下這個。

Answer 1

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
 ));
