Actually no, there isn't a smarter way to write this (without visiting Y twice) given the X that myTable. X and myTable. YY matches to may not be from the same row.
It will probably not be particularly efficient to try to write this query by only referencing Y once. However, given that you are using SQL Server 2008, there are variations that can be used.
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.
