=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>, 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
L</connect_call_use_softcommit> (see L</CAVEATS>) for your code to function
correctly with this driver. Otherwise you will likely get bizarre error messages
-such as C<no statement executing>.
-
-For ODBC support, see L<DBIx::Class::Storage::DBI::ODBC::Firebird>.
+such as C<no statement executing>. The alternative is to use the
+L<ODBC|DBIx::Class::Storage::DBI::ODBC::Firebird> driver, which is more suitable
+for long running processes such as under L<Catalyst>.
To turn on L<DBIx::Class::InflateColumn::DateTime> support, see
L</connect_call_datetime_setup>.

workaround for the C<no statement executing> errors, this of course adversely
affects performance.
-=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 with ODBC.
+Alternately, use the L<ODBC|DBIx::Class::Storage::DBI::ODBC::Firebird> driver.
