    Thanks Kevin

    Will read through it tomorrow.

    Interested to read how to get info back in a query that requires more than a plain join.

    Do the functions have the word "BEGIN" in them? If they do and they're in the FROM clause, then they are mTVFs (Multi-Statement Table Valued Functions) and not iTVFs (Inline Table Valued Functions). mTVFs are usually worse than even scalar functions.

    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.
