存儲過程，將輸出分組到一個新列

Question

我有下面這個存儲過程，它允許我選擇一個問題ID並列出用戶名和他們的答案。

我會怎麼改變它，所以它只能說明我的問題ID與新列稱爲總如下

CREATE PROCEDURE dbo.report 
    @Question_ID varchar(5) 
AS 
    SELECT * FROM submit_Answer 
    WHERE Question_ID=@Question_ID 

謝謝！

使用它可以爲每個Question_ID和Answer獲取一行，並計算Total列中發生的次數。

CREATE PROCEDURE dbo.report 
    @Question_ID varchar(5) 
AS 
    SELECT Question_ID, 
     Answer, 
     COUNT(*) as Total 
    FROM submit_Answer 
    WHERE Question_ID=@Question_ID 
    GROUP BY Question_ID,
