Take several 'userID's out of WHERE statement and putting into variable?

You can use a temporary table, there is more info: http://www.simple-talk.com/sql/t-sql-programming/temporary-tables-in-sql-server.

Use of table variables should work for you.

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.
