使用SEDE修改查询以处理多个用户

Question

我很难让我的查询做我想做的事.

如果我为一个UserId: 2140173运行它，它似乎运行良好。

Select UserId, 
(Select Count(VoteTypeId) From SuggestedEditVotes where UserId = 2140173) as 'Total',
(Select Count(VoteTypeId) From SuggestedEditVotes where UserId = 2140173 and VoteTypeId = 2) As 'Accepted',
(Select Count(VoteTypeId) From SuggestedEditVotes where UserId = 2140173 and VoteTypeId = 3) As 'Rejected'

from SuggestedEditVotes

    inner join Users on SuggestedEditVotes.UserId = Users.Id

where Users.Reputation > 2000 and UserId = 2140173

group by UserId

having Count(VoteTypeId) > 0

它回来了

UserId    Total    Accepted    Rejected
2140173    2230        1145        1085

但是，当我试图稍微修改它并为所有有2000多个信誉的用户运行它时，它并没有给出正确的结果:/

我被分选择语句困住了，因为我不知道应该在它们的where子句中放什么。

这是我尝试过的，但是它返回总数，我希望它是每个用户Id的计数。

Select UserId, 
(Select Count(VoteTypeId) From SuggestedEditVotes) as 'Total',
(Select Count(VoteTypeId) From SuggestedEditVotes where VoteTypeId = 2) As 'Accepted',
(Select Count(VoteTypeId) From SuggestedEditVotes where VoteTypeId = 3) As 'Rejected'

from SuggestedEditVotes

    inner join Users on SuggestedEditVotes.UserId = Users.Id

where Users.Reputation > 2000

group by UserId

having Count(VoteTypeId) > 0

有人能帮忙吗？

试试这个：

SELECT UserId,
 COUNT(VoteTypeId) AS 'Total',
 COUNT(
 CASE
   WHEN VoteTypeId = 2
   THEN VoteTypeId
   ELSE NULL
 END) AS 'Accepted',
 COUNT(
 CASE
   WHEN VoteTypeId = 3
   THEN VoteTypeId
   ELSE NULL
 END) AS 'Rejected'
FROM SuggestedEditVotes
INNER JOIN Users
ON SuggestedEditVotes.UserId = Users.Id
WHERE Users.Reputation       > 2000
GROUP BY UserId
HAVING COUNT(VoteTypeId) > 0
