mysql max函数使用的注意点

SELECT id,visits FROM `zentao`.`zt_user`

SELECT id,max(visits) FROM `zentao`.`zt_user`

如下图：结果查出的id不是max对应的id

 应该改为

SELECT id,visits FROM `zentao`.`zt_user` where visits = (SELECT max(visits) FROM `zentao`.`zt_user`) limit 1

SELECT id,visits FROM `zentao`.`zt_user` order by visits desc limit 1
