Question

MySQL查询用户表中所有记录，按ID降序排序，如果用户状态为0(未激活)，则注册时间升序，排在结果最后，这个SQL.该怎么写呢？

Answer 1

Assume status=1 is activated, 0 is not activated
select *from user order by status desc,case status when 1 then id end desc,case status when 0 then created_at end asc;

Answer 2

select * from user order by id ASC , status ASC , register_time ASC;This is the effect you want, if it doesn’t suit me I will change it

Answer 3

(select from user where status=1 order by id desc) union all (select from user where status=0 order by register_time asc)
