Question

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

为了根据输入生成排序结果，我使用临时表。

我的问题是，当提供的列是datetime时，则排序不起作用。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

 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详细信息

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

Sample Exec

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

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

获得的结果

预期结果

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

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

我面临的问题是当数据类型是datetime时如何正确排序数据？

先谢谢你的帮助....

Answer 1

您正在转换＆＃39; V.EULAVersionUpdateDate＆＃39;到日期DataType（...THEN convert(date, V.EULAVersionUpdateDate,103)），使用DATETIME数据类型进行转换

THEN convert(DateTime, V.EULAVersionUpdateDate,103)

使用临时表对存储过程中的日期时间行进行排序
