Hi Adam, one stupid question. What difference does it make in your example, if this one columne has a primary key? I my opinion it would make sense to update all fields, which contain 1. But I am only a user, not a programmer :-) Raphael > Without a primary key it is not possible to determine that a given row > is unique.
