Question

我正在创建一个电子商务基准网站。我的GETSITES存储过程中存在一些问题：

代码：

CREATE PROC USER_S_GETSITES
   @CategoryID int,
   @List int,
   @IsPopular bit,
   @MaxID int,
   @Status bit,
   @Word text
AS
    SELECT s.*, c.*, AVG(r.Rate) AS RateAVG, Count(r.ID) AS RateCount 
    FROM Sites AS s
    INNER JOIN Rates AS r ON r.SiteID = s.ID
    INNER JOIN Categories AS c ON c.ID = s.CategoryID
    WHERE (@CategoryID is NULL) OR s.CategoryID = @CategoryID
      AND (@MaxID is NULL) OR s.ID < @MaxID
      AND (@Status is NULL) OR s.Status = @Status
      AND r.Status=1
      AND (@Word is NULL) OR s.Name LIKE @Word OR s.Description LIKE @Word
      AND (@IsPopular is NULL) OR s.IsPopular=@IsPopular 
ORDER BY
    CASE @List WHEN 1 THEN s.ID END ASC,
    CASE @List WHEN 2 THEN s.ID END DESC,
    CASE @List WHEN 3 THEN RateAVG END DESC,
    CASE @List WHEN 4 THEN RateCount END DESC

我的问题：

消息8120，级别16，状态1，过程USER_S_GETSITES，第9行
  列'Sites.ID'在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中   消息207，级别16，状态1，过程USER_S_GETSITES，第23行
  列名称“RateAVG”无效。
  消息207，级别16，状态1，过程USER_S_GETSITES，第24行
  列名称“RateCount”无效。

我无法解决这些问题。我该怎么办？

Answer 1

错误1：在Sites.ID条款GROUP BY中包含列group by Sites.ID, ....，如CASE @List WHEN 3 THEN AVG(r.Rate) AS RateAVG END DESC

错误2：CASE @List WHEN 4 THEN Count(r.ID) AS RateCount END DESC

错误3：{{1}}

SQL查询存储过程错误
