    The problem is that your desired results require that your TABLE1 be sorted in a specific order, but the data provided is insufficient to enforce that order. You have to remember that there is no default order by in a set.

    Hence all the ROW_NUMBER() functions in my efforts so far.

    But it doesn't matter if two #Table2 rows have the same Date and Text - as the outcome is the same whichever is chosen as the match.

    But you DO have something to guarantee the order you want in the form of IDENTITY columns.

    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.
