表A: id name sex date 1 a 男 20220222 ··· ··· ·· 2011 b 男 20220222 ······· 查询 满足sex = 男 的第二条语句: select * from A where sex= "男" limit 1,1; 修改 满足sex = 男 的第二条记录 name = c update A set name = c where id = (select id from (select id from A where sex= "男" limit 1,1) as temp_A)
注意:
1. update 不能直接使用limit 1,1 ,select可以
2. update 不能对同一个表查询再修改,下面这条sql也是报错的
update A set name = c where id = (select id from A where sex= "男" limit 1,1)
3. 使用临时表,解决2中问题
update A set name = c where id = (select id from (select id from A where sex= "男" limit 1,1) as temp_A)
