  $results = _views_calc_fields();
  while ($calc_field = db_fetch_array($results)) {
    if ($fieldinfo['cid'] == $calc_field['cid']) {
      foreach (explode(',', $calc_field['tablelist']) as $table) {
        $query
          ->ensure_table($table);

      $query
        ->add_field("(" . $calc_field['calc'] . ") AS _cid" . $calc_field['cid'], NULL);
