=head1 NAME

DBIx::Custom::MySQL - DBIx::Custom MySQL implementation

=head1 SYNOPSYS

    # New

    my $dbi = DBIx::Custom::MySQL->new(user => 'taro', $password => 'kliej&@K',

                                       database => 'sample_db');

=head1 METHODS

You can use all methods of L<DBIx::Custom::Basic>

=head2 connect

Connect to database

    $self->connect;

If you set database, host, or port, data source is automatically created.

=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;

This is equal to MySQL function
