如何在不使用动态SQL的情况下在存储过程中使用Order By

Question

我有以下MS SQL存储过程.我需要在不使用动态SQL和sp_executesql方法的情况下对结果进行排序

@Order由可具有的可能值ProductName ASC,ProductName DESC,ProductCode ASC,VendorName DESC,VendorCode或ClientName

我试图使用ORDER BY CASE,是否有任何问题,如果 ProductName,ProductCode是不同的类型？

ALTER PROCEDURE [dbo].[SortedReport]
(
    @ClientID INT,
    @RecordLimit,
    @FromDate DATETIME,
    @ToDate DATETIME,
    @OrderBy NVARCHAR(MAX)
)

AS
BEGIN

IF (@OrderBy IS NULL) BEGIN
    SET @OrderBy = 'ProductName';
END    

SELECT TOP (@RecordLimit) 
        sv.ClientID,
        sv.VendorID,
        sv.ProductID,
        sv.TransactionTime,
        sv.ClientName,
        sv.VendorName,
        sv.ProductName,
        sv.ProductCode,
        sv.VendorCode,
FROM SortedReportiew AS sv 
WHERE (sv.ClientID = @ClientID)
    AND (sv.TransactionTime >= @FromDate)
    AND (sv.TransactionTime < @Date)

更新:

以下部分是否正确？从这里开始

ORDER BY 
    CASE @OrderBy WHEN 'ProductCode ASC' THEN ProductCode WHEN 'ProductCode DESC' THEN ProductCode END DESC,
    CASE @OrderBy WHEN 'ProductName ASC' THEN ProductName WHEN 'ProductName DESC' THEN ProductName END DESC,

Answer 1

如您所说:使用ORDER BY CASE,但多次以避免不同列类型的问题:

...
ORDER BY 
 CASE WHEN @OrderBy ='ProductName ASC' THEN sv.ProductName END,
 CASE WHEN @OrderBy ='ProductName DESC' THEN sv.ProductName END DESC,
 CASE WHEN @OrderBy ='ProductCode ASC' THEN sv.ProductCode END,
 CASE WHEN @OrderBy ='ProductCode DESC' THEN sv.ProductCode END DESC,
 CASE WHEN @OrderBy ='VendorName ASC' THEN sv.VendorName END,
 CASE WHEN @OrderBy ='VendorName DESC' THEN sv.VendorName END DESC,
 CASE WHEN @OrderBy ='VendorCode' THEN sv.VendorCode END,
 CASE WHEN @OrderBy ='ClientName' THEN sv.ClientName END

编辑:

更新了查询以适合您更新的问题.我假设你的意思是ProductCode ASC 和 ProductCode DESC？
