请帮我解决我的问题。 我正在使用SQL Server 2005，我完成了一个查询，然后我得到了如下数据
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
但我想要这样的数据如下
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
所以请帮助我获取这样的数据。

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

我使用stuff来获取列名，然后使用这些列来获得结果
然后我使用2个枢轴来获得Qty和Unique_Number的结果，然后加入两个结果以获得所需的结果
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 'D','January', 2014, 1500, 1236978

Declare @cols1 as nvarchar(max)
