SQL：查找大多數評論的用戶

Question

我需要找出發佈了最多評論數的用戶。有兩個表1）用戶（Id，DisplayName）2）評論（Id，UserId，測試）。我已經使用了以下查詢

Select DisplayName from users INNER JOIN (Select UserId, max(comment_count) as `max_comments from (Select UserId, count(Id) as comment_count from comments group by UserId) as` T1) as T2 ON users.Id=T2.UserId 

但是，這返回給我的Id = 1，而不是我想要的用戶的顯示名稱。我如何解決這個問題？

Answer 1

SELECT TOP 1 
U.DisplayName, 
COUNT(C.ID) AS CommentCount 
FROM 
Users AS U 
INNER JOIN Comments AS C ON U.ID = C.UserID 
GROUP BY 
U.DisplayName 
ORDER BY 
COUNT(C.ID) DESC
