                INNER JOIN c_module_details cmd
                  ON (cmd.module_code = bm.module_code
                    AND cmd.module_version = bm.module_version)
              WHERE bm.ukc = ?
              ORDER BY module_code";

$res = ingres_query($con, $query, array("08000473"));

echo("fetching\n");//test

     while($res && ($row = ingres_fetch_array($res)))
