=head1 Object methods

=head2 connect

This override L<DBIx::Custom> connect.

    # Connect to database
    $dbi->connect;

If database attribute is set, automatically data source is created and connect

=head2 connect_memory

    # Connect memory database
    $self = $dbi->connect_memory;

=head2 reconnect_memory

    # Reconnect memory database
    $self = $dbi->reconnect_memory;

=head2 last_insert_id

    # Get last insert id
    $last_insert_id = $self->last_insert_id;

This is equal to SQLite function

    last_insert_rowid()
