Mysql 同组查询

Mysql query with group

我有以下 table:

id  club_id club_option_id created
---|-------|--------------|-------
1  | 1     | 2            | 2015-02-11 16:31:23
2  | 1     | 3            | 2015-02-11 16:31:23
3  | 2     | 2            | 2015-03-06 08:16:02

我想select俱乐部(club_id)有两个选项(2和3)

我没有得到以下查询的任何结果:

SELECT club_id FROM 
club_options_to_clubs 
WHERE club_option_id = 2 AND club_option_id = 3  
GROUP BY club_id

我怎样才能得到 club_id 1 作为结果?

您可以按照以下方式进行 -

select 
t1.club_id from table_name t1
where t1.club_option_id = 2
and exits (
  select 1 from table_name t2
  where t1.club_id = t2.club_id
  and t2.club_option_id = 3
)

另一种方式是

select club_id from table_name
where club_option_id in (2,3)
group by club_id 
having count(*) = 2

使用上述方法,如果您需要检查多个 club_option_idin 函数中传递它们,然后使用 having count(*) = n 中的数字 这里 n = in 函数中的项目数。
