Reversed In?

    If this is covered somewhere else, sorry I did search though 🙂

    I was looking for a specific value across multiple columns in the same table and thought I'd try using the traditional in statement in reverse.

    select * from [some table] where 'X' in(col1, col2, col3);

    It seems that the compilier just boils INs to ORs?

    Yup, and it does that whether it's column IN (1,2,3) or 1 IN (Col1, Col2, Col3)
