Hi All,

--Unpivot the table.
SELECT VendorID, Employee, Orders
FROM
(SELECT VendorID, Emp1, Emp2, Emp3, Emp4, Emp5
FROM pvt) p
UNPIVOT
(Orders FOR Employee IN
(Emp1, Emp2, Emp3, Emp4, Emp5)
)AS unpvt

In above Query how can i dynamically get the Emp1,Emp2,Emp3.... columns which are mentioned in UNPIVOT Clause and SELECT clause from table itself.
Because my table structure may change.
Is it possible? If not if that is the requirement what are the alternative ways.
Plz tell me.
