I think you are falling into the trap of thinking that -R will operate
on '.' as though it had been included in your argument list. Descent
into sub directories will only occur if the *.db expands into at least
one argument which is a directory, whereupon its sub directories will be
explored.

Note that it would list all the contents of such sub directories, it
wouldn't prepend the directory name to your *.db.

This is because you should have put single quotes around the *.db

like
    find . -name '*.db'

to avoid shell expansion of the *.db
