Is there a way to select columns without Sql:: and database views?

Hello,
Each time I need to reduce overhead related to too many unneeded columns I've to create a database view and fetch from this view. The question is: is there a way to set output columns?

I tried this ( from issue #24):

    $mapper->bill_notice_list = c\Filtered::by('description', 'next_notification_date')->bill_notice();
    $billNotices = $mapper->bill_notice_list(
        array('usercustomer_id' => $usercustomerId)
    )->fetchAll();

but no data retrieved.

Start by reviewing the filtered column-selection example in the issue and the existing query and fetch behavior it describes. Determine whether selecting output columns is supported and what should happen when the attempted expression returns no data; done means a documented, working way to retrieve only the requested columns.
