Mysql更新脚本以更改值[重复]

Question

我有一个像

这样的值的表

Book ID    email1               email2
101        abcd@test.com     abcd@test.com
102        vxyz@test.com     vxyz@test.com
105        pqrs@test.com     pqrs@test.com

我想更新 email1 和 email2 的所有值 从 test.com 到 testmail.com

e.g abcd@test.com  to abcd@testmail.com,
and  vxyz@test.com   to   vxyz@testmail.com  

如何在 mysql 中为此编写更新查询

Answer 1

UPDATE table_name 
SET email1 = REPLACE(email1,'@test.com ','@testemail.com '), 
    email2 = REPLACE(email2,'@test.com ','@testemail.com ')
