+The following methods can be called via the func() method with a little tweak, but the use of func() method is now discouraged by the L<DBI> author for various reasons (see L<DBI's document|http://search.cpan.org/dist/DBI/lib/DBI/DBD.pm#Using_install_method()_to_expose_driver-private_methods> for details).
