Yii中的数据库事务的使用方法小结

Yii框架是支持数据库事务处理的,关于事务,这里就不多说了,想要了解的读者可以参看本站文章:

关于数据库(MySQL)事务

在项目中遇到批量删除的地方一般会使用到事务,下面列举一个用法实例与大家分享。

<?php
$array=array(
	0=>array('username'=>'phpernote.com_0','password'=>'123456'),
	1=>array('username'=>'u_1','password'=>'123456'),
	2=>array('username'=>'u_2','password'=>'123456')
);
$transaction=Yii::app()->db->dbConnection->beginTransaction();
//此处db代表的是定义在main.php中的数据库连接对象db
try{
	Yii::app()->db->createCommand()->insert('tbl_user',$array[0]);
	Yii::app()->db->createCommand()->insert('tbl_user',$array[1]);
	Yii::app()->db->createCommand()->insert('tbl_user',$array[2]);
	$transaction->commit();
}catch(Exception $e){
	$transaction->rollback();
}
Copy after login

注意:如果你使用的是MySQL数据库,那么表引擎必须是innodb类型的,因为MySQL数据库的MyISAM引擎不支持事务处理,所以如上代码不会达到预想的目的。
