if I have two databases, is possible to limit the access of one user only
at the own db and to avoid, for example, if it use a sql injection can in
some way from its db to modify the other?
so at max it can only damage its database.
which setting is preferable use?(example with phpmyadmin)

You should set correct privileges:
