本文實例講述了Yii使用DeleteAll連表刪除出現報錯問題的解決方法。分享給大家供大家參考，具體如下：
刪除數據的時候，經常會遇到連聯判斷刪除數據的條件，今天用Yii 的CDbCriteria生成關連條件。批量刪除的時候數據庫報錯。
頁面代碼為：
$criteria=new CDbCriteria;$criteria->join = ' LEFT JOIN {{positions}} p ON p.zpo_id=t.zpo_id ';$criteria->addCondition("p.zpo_type=1");$criteria->addCondition("t.zpl_content_id in ($id)");PosLog::model()->deleteAll($criteria);錯誤SQL為：
正確SQL語句應為：
追溯到Yii 基類：
framework/db/schema/CDbCommandBuilder.php#166
public function createDeleteCommand($table,$criteria){ $this->ensureTable($table); $sql="DELETE FROM {$table->rawName}"; $sql=$this->applyJoin($sql,$criteria->join); $sql=$this->applyCondition($sql,$criteria->condition); $sql=$this->applyGroup($sql,$criteria->group); $sql=$this->applyHaving($sql,$criteria->having); $sql=$this->applyOrder($sql,$criteria->order); $sql=$this->applyLimit($sql,$criteria->limit,$criteria->offset); $command=$this->_connection->createCommand($sql); $this->bindValues($command,$criteria->params); return $command;}解決方案。修改基類方法：
public function createDeleteCommand($table,$criteria,$alias='t'){ $this->ensureTable($table); $alias=$this->_schema->quoteTableName($alias); if(empty($criteria->join)){ $sql="DELETE FROM {$table->rawName}"; }else{ $sql="DELETE $alias FROM {$table->rawName} $alias"; } $sql=$this->applyJoin($sql,$criteria->join); $sql=$this->applyCondition($sql,$criteria->condition); $sql=$this->applyGroup($sql,$criteria->group); $sql=$this->applyHaving($sql,$criteria->having); $sql=$this->applyOrder($sql,$criteria->order); $sql=$this->applyLimit($sql,$criteria->limit,$criteria->offset); $command=$this->_connection->createCommand($sql); $this->bindValues($command,$criteria->params); return $command;}希望本文所述對大家基于Yii框架的PHP程序設計有所幫助。
