ASP.NET SQL查询帮助需要

我有一个结果，这样从SQL查询ASP.NET SQL查询帮助需要

Month Day Customer  Item 
------------------------------------------ 
January 1 John   Pencil 
January 1 Jack   --- 
January 1 Steve  Stapler 
January 2 John   --- 
January 2 Jack   --- 
January 2 Steve  VisitingCard 
January 3 John   --- 
January 3 Jack   Marker 
January 3 Steve  --- 
January 4 John   --- 
January 4 Jack   --- 
January 4 Steve  --- 
January 5 John   Scrapbook 
January 5 Jack   --- 
January 5 Steve  --- 
.... 
.... 
.... 
February 1 John   --- 
February 1 Jack   --- 
February 1 Steve  Marker

我想这是在一个asp.net的GridView可以表示为下面

       January 
Customer 1 2 3 4 5 6 7 8 9 10 11 ... 25 26 27 28 29 30 31 
--------------------------------------------------------- 
John  P - - - N - - - - -- --  -- -- -- -- -- -- -- 
Jack  - - M - - - - - - -- --  -- -- -- -- -- -- -- 
Steve S V - - - - - - - -- --  -- -- -- -- -- -- -- 
          February 
Customer 1 2 3 4 5 6 7 8 9 10 11 ... 25 26 27 28 
------------------------------------------------ 
John  - - - - - - - - - -- --  -- -- -- -- 
Jack  - - - - - - - - - -- --  -- -- -- -- 
Steve M - - - - - - - - -- --  -- -- -- --

我如何在SQL Server 2005或asp.net 2.0中完成这项工作？

请为PIVOT提供示例查询，因为它需要使用一些聚合函数。
