This would normally be done inside your programming language. However it might be possible to enforce the rule inside SQLite using a TRIGGER: <http://www.sqlite.org/lang_createtrigger.html> It might looks something like CREATE a TRIGGER UPDATE ON Country WHEN new.name != old.name BEGIN RAISE (FAIL, 'Not allowed to change the name of a country.') END Note: I just made that up off the top of my head and have no idea whether it will work. You will have to guard against (A) people DROPping the TRIGGER, and (B) people deleting the row from the Country table and making a new one with a different name.
