The most efficient way is to do the UPDATE then do an INSERT if rowcount is zero as explained in this previous answer .
(First of all - I would not try to avoid stored procedures, if there is no strong reason. The give a good benefit in most cases.).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. 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.
