    Please consider using a Tally Table instead of a recursive CTE to count. Please see the following article as to why.

    If you don't know what a Tally Table (or Tally CTE) is or how it can be used to replace certain loops (including the loops of a recursive CTE which are frequently slower than WHILE loops), please see the following article.

    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.
