=head1 NAME

DBIx::Custom::SQLite - DBIx::Custom SQLite implementation

=head1 SYNOPSYS

    use DBIx::Custom::SQLite;
    
    # New
    my $dbi = DBIx::Custom::SQLite->new(user => 'taro', $password => 'kl&@K',
                                        database => 'sample');
    
    # Connect memory database
    my $dbi->connect_memory;
    

=head1 METHODS

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

=head2 connect

Connect to database

    $dbi->connect;

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

=head2 connect_memory

Connect memory database

    $dbi->connect_memory;

=head2 reconnect_memory

Reconnect to memory databsse

    $dbi->reconnect_memory;

=head2 last_insert_rowid

Get last insert id

    $last_insert_rowid = $dbi->last_insert_rowid;
    
The folloing is last_insert_rowid sample.

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

This is equal to SQLite function

    last_insert_rowid()
