Yii: Getting data on the basis of highest average rating

Question

I am a yiibie and I want to get the top 5 ngo's from my "NgoRateReviewNgo" table. The condition for the top 5 Ngo's is that it should first find the average rating of the Ngo's and after that those 5 Ngo's which have highest average rating gets displayed. This is the code for my view file and contains the SQL query

  <div class="main">
    <div class="banner">
<img src="<?php echo Yii::app()->request->baseurl;?>/img/stat1.jpg" style="width: 1170px">

    <div class="container" style="background-color:#7AC5CD">

Answer 1

this should be the query

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