=head1 NAME

DBIx::Custom::MySQL - Implementation for MySQL

=head1 SYNOPSYS

    # Connect to database
    my $dbi = DBIx::Custom::MySQL->connect(user     => 'taro', 
                                           password => 'kliej&@K',
                                           database => 'your_database');
    
    # Get last insert id
    my $id = $dbi->last_insert_id;

=head1 ATTRIBUTES

This class is L<DBIx::Custom> subclass.
You can use all attributes of L<DBIx::Custom>

=head2 C<database>

    $dbi      = $dbi->database('your_database');
    $database = $dbi->database;

Database name.
This is used for connect().

=head2 C<host>

    $dbi  = $dbi->host('somehost.com');
    $host = $dbi->host;

Database host name.
You can also set IP address, instead of host name.
This is used for connect().

    $dbi->host('127.03.45.12');

=head2 C<port>

    $dbi  = $dbi->port(1198);
    $port = $dbi->port;

Database port. This is used for connect().

=head1 METHODS

This class is L<DBIx::Custom> subclass.
You can use all methods of L<DBIx::Custom>.

=head2 C<connect (overridden)>

    $dbi = DBIx::Custom::MySQL->connect(
        data_source => "dbi:mysql:database=books;host=somehost;port=2000"
    );
    
    $dbi = DBIx::Custom::MySQL->connect(user     => 'taro', 
                                        password => 'kliej&@K',
                                        database => 'your_database',
                                        host     => 'somehost',
                                        port     => 2000);

Connect to database. You can also specify database, host, and port
(instead of data soruce).

=head2 C<last_insert_id>

    $last_insert_id = $dbi->last_insert_id;

Get last insert id.
This is equal to MySQL last_insert_id() function.
