如何 select 满足 SQL 中某些条件的同一用户的多行？

Question

A有以下数据

id user_id visited_country
1  12      Spain 
2  12      France
3  14      England
4  14      France
5  16      Canada
6  14      Spain 

我想要 select 所有访问过西班牙和法国的用户。 我怎样才能在 MySQL 中做到这一点？

Answer 1

像下面这样的东西就足够了：

select user_Id
from t
where visited_country in ('Spain','France')
group by User_Id
having Count(distinct visited_country) = 2;

Answer 2

@Aman：如果你想排除英格兰，那就是

select distinct user_Id
from table
where visited_country in ('Spain','France')
and not exists
(Select distinct user_id
 From table where visited_country in ('England'))
group by User_Id
having Count(distinct visited_country)> = 2;
