I used to be able to do this (or at least I think I did). What I did was I added a field to a table. I named this table the same as the primary key in another table, and then enforced referential integrity. Everything works...but the problem is the new table does not have the values that exist in the other table for this ID. How do i update the related table so that the field I created will have the same values as those in the primary table?
