    Hi All,

    How to troubleshoot blocking if u r seeing multiple blocking chains? Do I need to kill all the head blockers?

    What is the best approach to deal with multiple blocking chains?

    Thanks,

    Sam

    Some blocking isn't just normal, it's required. The question here is "How long does each blocking chain last"?

    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.
