Recent versions of SQL Server have a PIVOT function. Here is an example of how to do pivoting in several SQL Server versions. And there are many good answers to this very popular SO question: SQL Server PIVOT examples?
Here is an example from that page of what a simple PIVOT statement looks like: SELECT act AS 'Action', View as 'View', Edit as 'Edit' FROM ( SELECT act, cmd FROM data ) AS src PIVOT ( MAX(cmd) FOR cmd IN (View, Edit) ) AS pvt.

A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
