    Thanks all. The CTE and rbednarek's solution both worked.

    The question now is, what did the changes do to performance and resource usage? The reason I ask is that a common technique for fixing performance and resource usage problems associated with many "all in one queries" is to split up the query and put the essential "driver rows" into a temp table and include that in the join.

    To be sure, "Set Based" coding is the way to go but it doesn't mean "All in one query".

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
