If you are creating a new column then you're not going to hit any of the problems with generating sequential numbers. You do need, for the future, to consider what you would want to happen if you deleted a row from that table. Would you expect the numbers on the other rows to remain the same or would you expect rows after the deleted one to move down one ?
