SQL選擇多行驗證條件的用戶

Question

我有下表：

第一列包含Services_ID ，第二列包含Users_ID ，第三列表示用戶是否已啟用該服務。 我需要識別（一次是用戶）哪個用戶可以使用ID 4和5的兩種服務。

我用Mysql寫了那個查詢：

SELECT DISTINCT User 
  FROM tablexxx
 WHERE Service IN (4, 5)
   AND User NOT IN (SELECT User
                      FROM tablexxx
                     WHERE Service IN (4, 5)
                       AND Active = FALSE);

該查詢有效，但是，是否有更好的技術方法來編寫它？

正確的結果是：

Answer 1

select user
from your_table
where service in (4,5)
and active = TRUE
group by user
having count(distinct service) = 2

要么

select user
from your_table
group by user
having sum(active = TRUE and service = 4) > 0
   and sum(active = TRUE and service = 5) > 0
