    # New
    my $dbi = DBIx::Custom::MySQL->new(user => 'taro', $password => 'kliej&@K',
                                       database => 'sample_db');

=head1 See DBIx::Custom and DBIx::Custom::Basic documentation at first

=head2 last_insert_id

    $last_insert_id = $dbi->last_insert_id;

The folloing is last_insert_id sample.

    $dbi->insert('books', {title => 'Perl', author => 'taro'});
    $last_insert_id = $dbi->last_insert_id;
