    I also tried something similar..............:-P

    select ROW_NUMBER() over(order by id) , name From Table1

    union

    select ROW_NUMBER() over(order by id) +3, name From Table2

    Unfortunately, that presupposes the esoteric knowledge that you have 3 items in Table1. Not exactly flexible code.

    Also, since there is the possibility of duplicates between the two tables, the use of UNION could return incorrect results.

    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.
