=head1 NAME
-DBIx::Class::Storage::DBI::InterBase - Driver for the Firebird RDBMS
+DBIx::Class::Storage::DBI::InterBase - Driver for the Firebird RDBMS via
+L<DBD::InterBase>
=head1 DESCRIPTION
-This class implements autoincrements for Firebird using C<RETURNING> as well as
-L<auto_nextval|DBIx::Class::ResultSource/auto_nextval> sets the limit dialect to
-C<FIRST X SKIP X> and provides L<DBIx::Class::InflateColumn::DateTime> support.
+This driver is a subclass of L<DBIx::Class::Storage::DBI::Firebird::Common> for
+use with L<DBD::InterBase>, see that driver for general details.
You need to use either the
L<disable_sth_caching|DBIx::Class::Storage::DBI/disable_sth_caching> option or

=head1 CAVEATS
Alternately, use the L<ODBC|DBIx::Class::Storage::DBI::ODBC::Firebird> driver.
-=item *
-
-C<last_insert_id> support by default only works for Firebird versions 2 or
-greater, L<auto_nextval|DBIx::Class::ResultSource/auto_nextval> however should
-work with earlier versions.
-
-=item *
-
-Sub-second precision for TIMESTAMPs is not currently available when using the
-L<ODBC|DBIx::Class::Storage::DBI::ODBC::Firebird> driver.
