问题描述

我正在尝试通过这样做来更新MySQL数据库中一个表中的多行.而且它不起作用.

I'm trying to update multiple rows in one table in MySQL database by doing this. And its not working.

$query = "UPDATE cart SET cart_qty='300' WHERE cart_id = '21';
          UPDATE cart SET cart_qty='200' WHERE cart_id = '23';
          UPDATE cart SET cart_qty='100' WHERE cart_id = '24';";
mysql_query($query,$link);// $link is specified above

任何人都知道这是怎么回事.

Anyone know what is wrong with this.

推荐答案

来自 PHP文档:

;分隔SQL语句,因此如果要继续使用mysql_query函数,则需要分隔查询...

The ; separates SQL statements, so you need to separate the queries if you want to continue using the mysql_query function...
