-DBIx::Class::PK::Auto - Automatic Primary Key class
+DBIx::Class::PK::Auto - Automatic primary key class
=head1 SYNOPSIS
+__PACKAGE__->load_components(qw/Core/);
+__PACKAGE__->set_primary_key('id');
+
=head1 DESCRIPTION
-This class overrides the insert method to get automatically
-incremented primary keys.
+This class overrides the insert method to get automatically incremented primary
+keys.
-You don't want to be using this directly - instead load the appropriate
-one for your database, e.g. PK::Auto::SQLite
+ __PACKAGE__->load_components(qw/Core/);
-=head1 METHODS
+PK::Auto is now part of Core.
-=over 4
+See L<DBIx::Class::Manual::Component> for details of component interactions.
-=item insert
+=head1 LOGIC
-Overrides insert so that it will get the value of autoincremented
-primary keys.
+C<PK::Auto> does this by letting the database assign the primary key field and
+fetching the assigned value afterwards.

+The code that was handled here is now in Row for efficiency.

+=head2 sequence
Manually define the correct sequence for your table, to avoid the overhead
associated with looking up the sequence automatically.
