以日期顺序显示动态列的数据透视表

Question

我有一个数据透视表，为每一行创建2列，我希望按日期顺序进行操作。

Below is the data in the raw format 
------------------------------------------------------------- 
partnum | period | TotalQty  |  ToldSold 

005483-6 | 2015-08 | 100.00000000 | 389.379000 

0551105 | 2015-08 | 10.00000000 | 4560.773000 

0CT202305 | 2015-09 | 4.00000000 | 2285.430800 

0CTR00905 | 2015-10 | 2.00000000 | 654.305400 

183386-32 | 2016-01 | 20.00000000 | 75.060400 

24-175UV50| 2016-03 | 450.00000000 | 42.723000 

我有以下的代码来生成动态数据透视表

DECLARE @cols AS NVARCHAR(MAX), 
@colsName AS NVARCHAR(MAX), 
@query AS NVARCHAR(MAX) 

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(period +'_'+c.col) 
        from #orderhistory 
        cross apply 
        (
        select 'TotalQty' col 
        union all 
        select 'ToldSold' 
       ) c 
     FOR XML PATH(''), TYPE 
     ).value('.', 'NVARCHAR(MAX)') 
    ,1,1,'') 

select @cols 



select @colsName 
= STUFF((SELECT distinct ', ' + QUOTENAME(period +'_'+c.col) 
      +' as [' 
      + period + case when c.col = 'TotalQty' then ' QtySold]' else 'Total $ Sold]' end 
     from #orderhistory 
     cross apply 
     (
      select 'TotalQty' col 
      union all 
      select 'ToldSold' 
     ) c 
     FOR XML PATH(''), TYPE 
     ).value('.', 'NVARCHAR(MAX)') 
    ,1,1,'') 

select @colsName 

set @query 
= 'SELECT partnum, ' + @colsName + ' 
from 
(
    select 
    partnum, 
    period +''_''+col col, 
    value 
    from 
    (
    select partnum, 
     period, 
     cast(TotalQty as numeric(10, 2)) TotalQty, 
     cast(ToldSold as numeric(10, 2)) ToldSold 
    from #orderhistory 
) src 
    unpivot 
    (
    value 
    for col in (TotalQty, ToldSold) 
) unpiv 
) s 
pivot 
(
    sum(value) 
    for col in (' + @cols + ') 
) p 
order by partnum' 

execute(@query) 

它创建类似下面的

partnum 2016-02 QtySold 2015-08Total $ Sold 2015-11Total $ Sold 2015-12 QtySold 

005483-10 NULL NULL NULL 100.00 

005483-12 NULL NULL 1249.68 450.00 

005483-14 NULL NULL NULL 70.00 

005483-2 NULL NULL 1234.19 350.00 

005483-3 10.00 NULL NULL NULL 

数据我想看到的是头横跨去日期订单

partnum | 2015-08 QtySold | 2015-08 Total $ Sold | 2015-09 QtySold | 2015-09 Total $ Sold........ 

一直到我达到当前月份。

我想我需要在某处添加一个订单，我只是不知道在哪里。这是我的第一个多列动态数据透视表，所以我有点失落。我试过的每个地方都给了我一些错误。

任何帮助非常感谢！

你单子你@colNames数据..

SELECT @colsName = STUFF((
    SELECT DISTINCT 
      ', ' 
      + QUOTENAME(period + '_' + c.col) 
      + ' as [' 
      + period 
      + CASE WHEN c.col = 'TotalQty' THEN ' QtySold]' ELSE 'Total $ Sold]' END 
    FROM #orderhistory 
      CROSS APPLY (SELECT 'TotalQty' col UNION ALL SELECT 'ToldSold') c 
--ORDER BY HERE 
    ORDER BY period, c.col 
    FOR XML PATH(''), TYPE 
).value('.','NVARCHAR(MAX)'),1,1,'')
