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($criteria);
错误sql为：
delete from `zd_pos_log` left join zd_positions p on p.zpo_id=t.zpo_id where (p.zpo_type=1) and (t.zpl_content_id in (76))
正确sql语句应为：
delete t from `zd_pos_log` t left join zd_positions p on p.zpo_id=t.zpo_id where (p.zpo_type=1) and (t.zpl_content_id in (76))
追溯到yii 基类：
framework/db/schema/cdbcommandbuilder.php#166
public function createdeletecommand($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 $command;
}
解决方案。修改基类方法：
public function createdeletecommand($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;
}
希望本文所述对大家基于yii框架的php程序设计有所帮助。
