请帮我解决我的问题。我正在使用 SQL Server 2005，我做了一个查询，然后我得到如下数据

Name       Month        Year      Qty       Unique Number
A          October      2013      30000     4986975
B          October      2013      4378      2439257
C          October      2013      14575     8378872
D          October      2013      2400      1756443
A          January      2014      20000     1752369
D          January      2014       1500     1236978
A          February     2014       2000     1897606

但我想要这些数据，如下所示

Name            october-2013             January-2014            February-2014
                Qty     Number           Qty     Number          Qty      Number      
A              30000    4986975         20000    1752369         2000     1897606
B              4378     2439257           0         0             0         0
C              14575    8378872           0         0             0         0
D               2400    1756443          1500    1236978          0         0

所以请帮我获取这样的数据。

谢谢

我使用了一些东西来获取列名，然后使用这些列来获取结果

然后我使用 2 个轴来获取 Qty 和 Unique_Number 的结果，然后将这两个结果合并以获得所需的结果

select * into #tbl from (
Select 'A' NAME,'October' Month ,2013 Year ,30000 QTY, 4986975 Unique_NUmber
UNION SELECT 'B','October',      2013,      4378 ,     2439257
UNION SELECT 'C','October',      2013,      14575,     8378872
UNION SELECT 'D','October',      2013,      2400 ,     1756443
UNION SELECT 'A','January',      2014,      20000,     1752369
UNION SELECT 'D','January',      2014,       1500,     1236978
UNION SELECT 'A','February',     2014,       2000,     1897606
) A

Declare @cols1 as nvarchar(max)

Declare @cols2 as nvarchar(max)


set @cols1 = STUFF((        
        select col from (       
        select distinct ',['+MONTH+'-'+CAST(YEAR as varchar)+'-Qty]' col, DATEPART(MM,'01 '+Month + ' ' + CAST(YEAR as varchar)) MonthNumber ,year
        from #tbl group by year,DATEPART(MM,'01 '+Month + ' ' + CAST(YEAR as varchar)),',['+MONTH+'-'+CAST(YEAR as varchar)+'-Qty]'
                ) A
        for XML PATH(''), TYPE).value('.','NVARCHAR(MAX)') ,1,1,'')
set @cols2 = STUFF((        
        select col from (       
        select distinct ',['+MONTH+'-'+CAST(YEAR as varchar)+'-UN]' col, DATEPART(MM,'01 '+Month + ' ' + CAST(YEAR as varchar)) MonthNumber ,year
        from #tbl group by year,DATEPART(MM,'01 '+Month + ' ' + CAST(YEAR as varchar)),',['+MONTH+'-'+CAST(YEAR as varchar)+'-UN]'
                ) A
        for XML PATH(''), TYPE).value('.','NVARCHAR(MAX)') ,1,1,'')
--print @cols1

--select * from #tbl

declare @query as Nvarchar(max)

set @query='select A.*, B.* from 
            (select NAME, MONTH+''-''+CAST(YEAR as varchar)+''-QTY''MonthYear, QTY
            from #tbl) as A
            PIVOT
            (
            SUM(QTY)
            FOR MonthYear IN ('+ @cols1 +')
            ) AS A
            left join 
            (
            select * from 
            (select NAME, MONTH+''-''+CAST(YEAR as varchar)+''-UN''MonthYear, Unique_NUmber
            from #tbl) as A
            PIVOT
            (
            SUM(Unique_NUmber)
            FOR MonthYear IN ('+ @cols2 +')
            ) AS P ) B on A.Name=B.NAME
            '


execute(@query)

drop table #tbl

希望这会有所帮助：D

Microsoft SQL Server 有一个包含的数据透视函数。

使用它要容易得多。

那请看说明书。 使用 PIVOT 和 UNPIVOT

它在那里得到了很好的解释，包括一些样本。

create table table1 (Name varchar(20),[Month] varchar(10), [Year] varchar(10) , qty int, [Unique_Number] int);
