枢转多个列

我有两个SQL Server 2008中的表，在一个我有每周的文章的需求，在另一个我有股票，事端喜欢

需求：

Article Week Need -------------------------------------------------------------------- aa 1 25 aa 2 13 aa 4 33 aa 6 21 aa 25 40 ab 1 1 ab 2 3 ab 16 14 ab 50 50 

STOCKS

  Article Units --------------------------------------------------------------------------- aa 80 ab 14 ac 8 

我需要展示一些像：

  Article WEEK1 WEEK2 WEEK4 WEEK6 WEEK16 WEEK25 needs stock needs stock needs stock needs stock needs stock needs stock aa 25 80 13 55 42 22 21 20 0 -1 40 -1 ab 1 14 3 13 0 10 0 10 14 10 0 -4 

这将显示在Encel，为此，我使用C＃和T-SQL，我的问题是，如果使用PIVOT我可以oly做每周的需求，但我期望的需求和股票，如果我没有枢轴我可以获取本周股票的文章，将数据保存在对象中，并每周进行股票计算，然后格式化Excel，但我有一个问题，我需要在对象中的东西：

 puclic class needsPerWeek { string Article{get;set;} int needsWeek1{get;set;} int stockWeek1{get;set;} int needsWeek2{get;set;} int stockWeek2{get;set;} int needsWeek{get;set;} int stockWeek4{get;set;} int needsWeek6{get;set;} int stockWeek6{get;set;} int needsWeek16{get;set;} int stockWeek16{get;set;} int needsWeek25{get;set;} int stockWeek25{get;set;} int needsWeek50{get;set;} int stockWeek50{get;set;} .... .... } 

但是我不知道我有多less周才会重新开始。

那么，我可以做这个与枢轴吗？或者任何其他方式来获得这个？

只需复制并粘贴下面的代码，并根据您的需要做一些更改。 我们只是dynamic的列string（UnitsWeek1，UnitsWeek2，NeedsWeek1 …等）。 并且使用Pivot获得两个表格，并通过join两个表格来获得一张决赛桌。

 DECLARE @cols1 AS NVARCHAR(MAX), @query1 AS NVARCHAR(MAX), @cols2 AS NVARCHAR(MAX), @query2 AS NVARCHAR(MAX); select @cols1 = STUFF((SELECT distinct ',' + QUOTENAME('NeedsWeek'+Week) from NeedsMaster FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'') set @query1 = 'SELECT Article, ' + @cols1 + ' from ( select Article , Need ,''NeedsWeek''+Week as Week from NeedsMaster ) x pivot ( min(need) for Week in (' + @cols1 + ') ) p ' select @cols2 = STUFF((SELECT distinct ',' + QUOTENAME('UnitsWeek'+n.Week) from NeedsMaster n left join StocksMaster s on s.Article=n.Article FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'') set @query2 = 'Select * from (SELECT Article, ' + @cols2 + ' from ( select n.Article , s.Units ,''UnitsWeek''+n.Week as Week from StocksMaster s inner join NeedsMaster n on s.Article=n.Article ) x1 pivot ( min(Units) for Week in (' + @cols2 + ') ) p1 ) a inner join (SELECT Article, ' + @cols1 + ' from ( select Article , Need ,''NeedsWeek''+Week as Week from NeedsMaster ) x2 pivot ( min(need) for Week in (' + @cols1 + ') ) p2 ) b on a.Article=b.Article' execute(@query2) 

（@ query1只是为了更好的理解目的）。 试一试，我希望你会按照你的要求编辑它。
