in the insert/update/delete methods, use the corresponding object to build the query

@roygu, this is a backwards compat break for your patch to make it so that integer-keyed $cols are treated differently. that behavior has been removed. to get it back, do this:

    $update = $sql->update();
    $update->set('col', 'col + 1'); // SET col = col + 1

This should be a better long-term solution.  Sorry for the hassle.
