请教 Mysql事务回滚怎么写?
请教 Mysql事务回滚怎么写?
就是俺现在碰到一个问题:论坛扣币项目中,用户支付论坛币的时候如果突然断网、电脑死机、停电、等其它自然灾害时,导致本次交易没有成功(即用户的币已经扣掉了,但是服务器数据库中没有消费记录等其它情况),这种情况是用Mysql事务回滚处理吗?代码怎么写?还有别的办法吗?

――――期待前辈高手详解!

没有commit是不会生效的, 回滚是取消的意思, 不是提交的意思.

这个也没什么好讲的,网上大把的教程,找了一段给你自测,尝试着把sql写错然后看看效果

PHP code
mysql_query("BEGIN"); //或者mysql_query("START TRANSACTION");
$sql = "INSERT INTO ...";
$sql2 = "INSERT INTO ...";
$res = mysql_query($sql);
$res1 = mysql_query($sql2); 
if($res && $res1){
    mysql_query("COMMIT");
    echo '提交成功。';
}else{
    mysql_query("ROLLBACK");
    echo '数据回滚。';
}
mysql_query("END"); <div class="clear">
                 
              
              
        
            </div>
Copy after login
