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：

DELETE FROM `zd_pos_log` LEFT JOIN zd_positions p ON p.zpo_id=t.zpo_id WHERE (p.zpo_type=1) AND (t.zpl_content_id in (76))

正確SQL語句應為：

DELETE t FROM `zd_pos_log` t LEFT JOIN zd_positions p ON p.zpo_id=t.zpo_id WHERE (p.zpo_type=1) AND (t.zpl_content_id in (76))

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。
