本文实例讲述了Yii使用DeleteAll连表删除出现报错问题的解决方法。分享给大家供大家参考,具体如下:
删除数据的时候,经常会遇到连联判断删除数据的条件,今天用Yii 的CDbCriteria生成关连条件。批量删除的时候数据库报错。
页面代码为:

$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 ); |
错误SQL为:
正确SQL语句应为:
追溯到Yii 基类:

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 ; } |

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 ; } |
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
