    Jeff,

    >> So, you don't care what the non-primary key columns contain at all? In other words, you never have the need for an UPDATE?

    Correct. It's simply a matter of replacing the existing record.

    I'd go with the SAN Snapshot, if you have that available, then. It'll be faster than synching even just one table.

    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.
