存储过程，将输出分组到新列

Question

我在下面有这个存储过程，它允许我选择一个问题ID并列出用户名和他们的答案。

我如何更改它，以便只显示带有新列名为total 的问题ID，如下所示

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

谢谢！

使用此方法为每个Question_ID获取一行，并在总计列中回答并计算出现次数。

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,
