        $_query_parts  = array();
        $sep ="";
        for($x=0;$xprepare($_query);
       echo $_query;

        if (!$query_run->execute()) {
            $insertError = "There was an error inserting data: " . $query_run->error;
      print "affected rows:" . $query_run->affected_rows; //how many records affected?         

    }
  }
