Why would you want the db to do this? Why wouldn't you require the application to..[clipped]..the app takes care of the rest.
Philosophically, with this argument, why do you want the DB to have _any_ constraints at all?
Because I assume there are multiple apps, at least one is flawed, and at least some rows will sooner or later be entered another way.
