    Just a shot in the dark without being able to see the code, but if you're using the variable in any concatenation operation, you might want to set the CONCAT_NULL_YIELDS_NULL option off and try it again. With the option on, any concatenation with a NULL will change the entire string to NULL.

    Oh... absolutely correct but I wouldn't do it that way especially since it's already known that future versions of SQL Server will not have the option of turning it off. Better to use ISNULL() for such things.

    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.
