You had originally posted this as a single message at the end of this thread, where it made no sense to me. I've split it off into it's own thread.
Without a better understanding of your problem, I can't offer much of an answer.
If there are just some columns that aren't referenced in other tables (using FOREIGN KEY constraints), then just update the columns.
If you have a more complicated scenario, then you'll have to explain it in more detail before I can help you.
In theory, theory and practice are identical. In practice, theory and practice are unrelated.
