--取ID
select distinct id from tb group by id having count(*) > 1
--取ID,content
select * from tb where id in (select distinct id from tb group by id having count(*) > 1)
[解决办法]
select * from tb
where ID in (select ID from tb as t group by ID having(count(1)> =2))
[解决办法]
--1
select * from 表 where id in (select id from 表 group by id having(count(*))> 1)
--2
select * from 表 a where exists (select 1 from 表 where id=a.id group by id having(count(*))> 1)
--2
select * from 表 a where not exists (select 1 from 表 where id=a.id group by id having(count(*))=1)
