When you update a record, you aren't updating the actual id that is part of the foreign key relationship. Right?

So, what exactly are you wanting to have happen?

Your question is not entirely clear; but I'm guessing that you have a foreign key relationship between two tables, with both the UPDATE and DELETE set to "NO ACTION".

This will prevent you from deleting the parent record if any child records reference it.

It will also prevent you from updating the primary key of the parent record if any child record references it.

It will not prevent you from updating other columns on the parent record.

so if i set the primary key column as identity this future will not work correct i meant the update

Identity or not, you can't update the primary key of a parent record which is referenced by child records.

There is nothing to prevent you from updating the columns on the parent record which are not part of the primary key.
