Question

I have a result like this from an SQL query:

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

I’d like this to be represented in an ASP.NET gridview as below:

                             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 - - - - - - - - -- --     -- -- -- --

How can I get this done either in SQL Server 2005 or in ASP.NET 2.0?

Please give the sample query for PIVOT as it requires some aggregate function to be used.

Answer 1

You might want to use a tool like DevExpress which provides you with a pivot table. You can then bind the pivot table to your data and it does the work for you.
