如何通过单个mysql查询更新多个表? [英] How to update multiple tables by single mysql query?

问题描述

我有两个表tb1& tb2 我必须更新两个表的公共列，即user_level 我对两个表(如用户名)都有一个通用条件.

I have two tables tb1 & tb2 I have to update a common column of both tables, i.e user_level I have a common criteria for both tables like username.

所以我想这样更新:

UPDATE tb1, tb2 SET user_level=1 WHERE username="Mr.X"

但是以某种方式它不起作用. 什么是正确的mysql查询呢?

But somehow it is not working. What would be the correct mysql query for this?

推荐答案

尝试一下:

UPDATE table_1 tb1, 
       table_2 tb2, 
       table_3 tb3 
SET    tb1.field2 = "some value", 
       tb2.field3 = "some other value", 
       tb3.field4 = "some another value" 
WHERE  tb1.field1 = tb2.field1 
       AND tb1.field1 = tb3.field1 
       AND tb1.field1 = "value" 

我在MSAccess和SQL SERVER 2008上测试了代码

I tested the code on MSAccess and SQL SERVER 2008
