子查询返回错误答案

Question

我有两张桌子，比如 1:-用户

id  name
1   vivek
2   raj
3   mohan
4   gagan
5   priya

2：-购买

id  typee        user_id
1   class        1
2   class        1
3   course       1
4   class        2
5   test_series  3
6   test_series  2 

我正在尝试运行

select p.id,(select count(purchasee.user_id) as tot
             from purchasee
             where purchasee.user_id=p.id
             and typee='class'
             or typee='course' ) as classcourse,(select count(purchasee.user_id) as tot
                                                 from purchasee
                                                 where purchasee.user_id=p.id 
                                                 and typee='test_series') as test 
from purchasee as p
GROUP by p.user_id

查询及其刺激我

id      Classcourse    test
1       3              0
4       1              0
5       0              1

预期的答案是

id      Classcourse    test
1       3              0
4       1              1
5       0              1

我想选择用户购买（课程或课程）或（test_series），如果是，则用户购买课程或课程，然后计算它，或者如果用户购买 test_series，然后计算行数

Answer 1

试试下面的sql

SELECT p.id,
     SUM( IF( typeee = 'class' || typeee = 'course', 1,0) ) as tot,
     SUM( IF (typeee = 'test_series', 1,0) ) as classcourse
FROM purchasee as p
GROUP by p.user_id
