Du kan använda SQL Servers PIVOT operatör

SELECT  *
FROM    (
          SELECT  P.ProductName
                  , C.CustName
                  , T.Amount

                  INNER JOIN Customer AS C ON  T.CustomerID = C.CustomerID  
          WHERE   T.TranDate BETWEEN '2011-01-01' AND '2011-03-31'   
        ) s
PIVOT   (SUM(Amount) FOR ProductName IN ([Car], [Cycle], [Scooter])) pvt
