In general, I'm not sure how useful it is to know that you're
"starting over from scratch," since any database query needs to check
its result. Presumably, an app's behavior in the "no data" case is the
same regardless of *why* there's no data. 99% of the time the behavior
will be to reload the data from a server.
More importantly, what constitutes a corrupt database, and how to
recover from it, are serious implementation details. Some
implementations may have error correction algorithms. Others may have
backups they can restore. Others may have to wipe the database
completely and start over. Still others may not be able to start
anything. (For example, the storage medium might have gone bad, or
been locked or disconnected.) So, imposing a "start over from scratch"
requirement would hamper some implementations while requiring the
impossible of others.
