    15 Hours? It would appear that, in your case, denormalization for reporting puposes is the wrong thing to do. I'd consider a more normalized approach that uses performance tools such as pre-aggregation in sub-queries, well formed indexes, and a healthy dose of best practices for performance.

    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.
