question on unpivoting the table

It would really help if you provided the dataset that you want to UNPIVOT but here is a simple example for this set of data...

Which is generated with the following CTE SQL...

WITH aDataSet
AS
(
    SELECT 12345 [ProductID],
        62393.57 [2008SalesTotals],
        71141.45 [2009SalesTotals]
    UNION ALL
    SELECT 67890, 70996.23, 54378.33
    UNION ALL
    SELECT 23456, 98734.10, 53784.65
    UNION ALL
    SELECT 98765, 75893.54, 98756.54
    UNION ALL
    SELECT 98357, 42890.55, 63489.54
)

The UNPIVOT command would then look something like...

SELECT ProductID, SaleYear, SaleTotal FROM ( SELECT ProductID, [2008SalesTotals] [2008], [2009SalesTotals] [2009] FROM aDataSet ) AS udt

This would output a resultset like so...

I hope that helps you out.

The first place to look is BOL - PIVOT and UNPIVOT are explained here : http://msdn.microsoft.com/en-us/library/ms177410.aspx
