yii2 多表联查 where条件里 A表字段=B表字段怎么表示?
$res =self::find()->select(['a.id','a.name']) ->join('LEFT JOIN','b','b.qid=a.id') ->join('LEFT JOIN','c','c.uid=b.uid') ->where(['a.state'=>0,'b.state'=>0,'c.state'=>0,'c.uid'=>123456]) ->asArray()->all();
想在where条件里加上c.type=b.type怎么加???
解决方案
$query->andWhere(new \yii\db\Expression('c.type = b.type'))
