    I think the missing link here is join information between the two tables tblCurrentUser and tblPromo.

    perhaps this might work (if you file in the gaps):

    update tblPromo
    set tblPromo.PromoOperator = tblCurrentUser.UserName
    from tblPromo
    join tblCurrentUser
    on tblPromo.<pkid?> = tblCurrentUser.<fkid?>
    where tblPromoOperator is null

    I have assumed the tables are joined via pk and fk, but so long as a valid join and be made the join method should be valid.

    Cheers sduggan...
