=head1 NAME
Rose::DB::Generic - Generic driver class for Rose::DB.
=head1 SYNOPSIS
use Rose::DB;
Rose::DB->register_db(
dsn => 'dbi:SomeDB:...', # unknown driver
username => 'devuser',
password => 'mysecret',
);
Rose::DB->default_domain('development');
Rose::DB->default_type('main');
...
$db = Rose::DB->new; # $db is really a Rose::DB::Generic object
...
=head1 DESCRIPTION
This is the subclass that L<Rose::DB> blesses an object into (by default) when the L<driver|Rose::DB::Registry::Entry/driver> specified in the registry entry is has no class name registered in the L<driver class map|Rose::DB/driver_class>.
To maximize the chance that this class will work with an unsupported database, do the following.
=over 4
=item * Use a L<driver|Rose::DB::Registry::Entry/driver> name that exactly matches the L<DBI> "DBD::..." driver name. Even though L<Rose::DB> L<driver|Rose::DB::Registry::Entry/driver>s are case-insensitive, using the exact spelling and letter case will allow this generic L<Rose::DB> driver to connect successfully.
=item * Specify the DSN explicitly rather than providing the pieces separately (host, database, port, etc.) and then relying upon this class to assemble them into L<DBI> DSN. This class will assemble a DSN, but it may not be in the format that an unsupported driver expects.
=back
This class inherits from L<Rose::DB>. See the L<Rose::DB> documentation for information on the inherited methods.
