存储过程中的日期时间与临时表排序

Question

我有一个存储过程，它从多个表（使用连接）中选择数据并根据提供的列以排序顺序（asc或desc）返回它。

为了生成基于输入的排序结果，我使用了临时表。

我的问题是，当提供的列是datetime，那么排序不起作用。 对于其他列，该过程按预期工作。

这是我使用的代码。

ALTER PROCEDURE [dbo].[usp_GetEULADetails] 
(
    @OrgKey INT 

    ,@FilterParams FilterTypes READONLY, 
    /*– Sorting Parameters */ 
    @SortColumn nvarchar(20) = 'Status' -- BranchCode 
    ,@SortOrder nvarchar(4) = 'Asc' 

    /*– Pagination Parameters */ 
    ,@PageNumber int = 0 
    ,@PageSize int = 0 


) 

AS 

BEGIN 

SET NOCOUNT ON; 

DECLARE @SortCol nvarchar(20), 
     @FirstRec int, 
     @LastRec int, 
     @TotalRows int, 
     @GlobalSearch nvarchar(100), 
     @EULAVersionNumber nvarchar(100) 

DECLARE @StatusKey INT =(SELECT dbo.GetStatusKey('ACTIVE')) 
DECLARE @RowCountSelected INT 

SELECT 
    @EULAVersionNumber = LTRIM(RTRIM(Value)) 
FROM @FilterParams 
WHERE [FieldName] = 'EULAVersions' 

SELECT 
    @GlobalSearch = LTRIM(RTRIM(Value)) 
FROM @FilterParams 
WHERE [IsGlobal] = 1 

SET @SortCol = LTRIM(RTRIM(@SortColumn)) 
SET @FirstRec = (@PageNumber - 1) * @PageSize 
SET @LastRec = (@PageNumber * @PageSize + 1)

--FilterTypes详细

CREATE TYPE [dbo].[FilterTypes] AS TABLE(
[FieldName] [varchar](100) NOT NULL, 
[Value] [varchar](800) NOT NULL, 
[IsGlobal] [bit] NULL DEFAULT ((0)) 
) 

样品Exec的

declare @FilterParams AS FilterTypes; 
insert into @FilterParams values('EULAVersions','',1) 

exec [usp_GetEULADetails] 2,@FilterParams,'EULAVersionUpdateDate','desc',0,0 

得到的结果

预期结果

declare @FilterParams AS FilterTypes; 
insert into @FilterParams values('EULAVersions','',1) 

exec [usp_GetEULADetails] 2,@FilterParams,'ContactFirstName','desc',0,0 

我所面临的问题是如何在数据类型为datetime的数据正确排序？

感谢提前的帮助....

Answer 1

要转换“V.EULAVersionUpdateDate”最新的数据类型（...THEN convert(date, V.EULAVersionUpdateDate,103)），使用日期时间数据类型转换

THEN convert(DateTime, V.EULAVersionUpdateDate,103)
