我有一个显示mysql查询结果的PHP页面。为每个返回的记录分配一个复选框，其值等于行ID列。
将mysql语句插入到新表中。
我想添加第二个mysql查询，用于更新所选ID匹配的另一个表的状态。查询如下：
UPDATE despgoods_alldetails，loaddetails SET despgoods_alldetails.locstatus ='LoadCreated'WHERE despgoods_alldetails.despgoodsid = $ val
当前有效的PHP代码页面（我知道一些不正确的代码）：

> mysql_connect("localhost", "hulamin_hulamin", "Hulamin2011")or die("cannot connect");
> mysql_select_db("hulamin_loc")or die("cannot select DB");

除了每个选定行的select语句外，如何添加我要运行的update语句？
感谢任何帮助。
谢谢和问候， 莱恩史密斯

你可以创建一个触发器，当数据保存在辅助表中时会触发;如果您认为这可能是您需要的，请查看mysql手册中的触发器

我虽然会在这里发布完整的工作代码。非常感谢@mishu的所有帮助和耐心。
