本文實(shí)例講述了Yii使用DeleteAll連表刪除出現(xiàn)報(bào)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(shù)據(jù)的時(shí)候，經(jīng)常會遇到連聯(lián)判斷刪除數(shù)據(jù)的條件，今天用Yii 的CDbCriteria生成關(guān)連條件。批量刪除的時(shí)候數(shù)據(jù)庫報(bào)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($criteria);
    錯誤SQL為：
    DELETE FROM `zd_pos_log` LEFT JOIN zd_positions p ON p.zpo_id=t.zpo_id WHERE (p.zpo_type=1) AND (t.zpl_content_id in (76))
    正確SQL語句應(yīng)為：
    DELETE t FROM `zd_pos_log` t LEFT JOIN zd_positions p ON p.zpo_id=t.zpo_id WHERE (p.zpo_type=1) AND (t.zpl_content_id in (76))
    追溯到Y(jié)ii 基類：
    framework/db/schema/CDbCommandBuilder.php#166
    public function createDeleteCommand($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(shè)計(jì)有所幫助。
