如何在数据透视中通过tgl排序，我在sql中有这样的代码。

ALTER PROCEDURE [dbo].[procshift]

@priode nvarchar(6),

@cols   nvarchar(max)='' ,

@query  nvarchar(max)=''

AS

BEGIN

select @cols = STUFF((SELECT distinct ',' + QUOTENAME((tgl)) 

                    from tblabsen where priode = @priode 

            FOR XML PATH(''), TYPE

            ).value('.', 'NVARCHAR(MAX)') 

        ,1,1,'')


set @query = 'SELECT [no_induk],priode, ' + @cols + ' 
            from 
            (
              select [no_induk], tgl, kodealasan,priode
              from tblabsen where priode = '''+@priode+'''    
            ) x
            pivot 
            (
                max(kodealasan)
                for [tgl] in (' + @cols + ')
            ) p '       
END
execute sp_executesql @query;

如果我执行此操作，则会得到这样的结果

no_induk priode 1-Feb-19 2-Feb-19 3-Feb-19    
100101   12019   P         P       P

显示数据不排序，如何通过tgl进行查询

no_induk priode 21-jan-19 22-jan-19 23-jan-19     
100101   12019   P         P         P

Answer 1

只需在生成列的语句中添加ORDER BY：

SET @cols = STUFF((SELECT ',' + QUOTENAME((tgl)) 
                   FROM tblabsen
                   WHERE priode = @priode 
                   GROUP BY tgl
                   ORDER BY tgl ASC
                   FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,'');

我还建议对动态语句进行参数化。将where priode = '''+@priode+'''更改为

WHERE priode = @priode

，然后将您的sp_executesql更改为：

EXEC sp_executesql @query, N'@priode nvarchar(6)', @priode = @priode;

编辑，我刚刚注意到，为什么@cols和@query在这里是参数？从参数列表中删除它们，然后DECLARE在您的SP中。

Answer 2

您可以尝试下面的代码以升序获取所有日期列。

DECLARE @cols   nvarchar(max)='' 
    SELECT @cols = COALESCE(@cols + '[', '')+ FORMAT(tgl,'dd-MMM-yyyy')+'],'
      FROM tblabsen
      GROUP BY date
      ORDER BY date 
       IF (LEN(@cols)>1)
      BEGIN 
      Set  @cols = STUFF(@cols, LEN(@cols), 1, '')
      END
