如何將聯接查詢添加到yii搜索功能

Question

我想知道的是，如何將聯接查詢添加到yii搜索功能。

搜索功能是在貨幣模型。（currency.php）

>public function search() 
    { 

     $criteria=new CDbCriteria; 

     $criteria->compare('id',$this->id,true); 
     $criteria->compare('name',$this->name,true); 
     $criteria->compare('sign',$this->sign,true); 

     return new CActiveDataProvider($this, array(
      'criteria'=>$criteria, 
     )); 
    } 

我想連接查詢添加到該函數。 更改爲MyQuery是這樣的：

SELECT * FROM 貨幣CUR INNER JOIN currency_option curopt ON cur.id = curopt.currency_id AND curopt.company_id = '$ com_id'。

任何人都請幫助我。非常感謝！

Answer 1

$criteria=new CDbCriteria; 
$criteria->join="INNER JOIN currency_option curopt ON cur.id = curopt.currency_id AND curopt.company_id = '$com_id'"; 
$criteria->compare('id',$this->id,true); 
$criteria->compare('name',$this->name,true); 
$criteria->compare('sign',$this->sign,true); 

試試這個。
