latest.lib에 그룹에 있는 최신글을 떙겨오는 부분

  $sql = "select a.*, b.bo_subject, c.gr_subject, c.gr_id from g5_board_new a, g5_board b, g5_group c where a.bo_table = b.bo_table and b.gr_id = c.gr_id and b.bo_use_search = 1 and c.gr_id = '{$gr_id}' and a.wr_id = a. wr_parent order by a.bn_id desc limit 0, {$rows}";

이 부분이있는데 이거 부분에서 wr_10이 on일경우에 만 나오게 하고싶은데 데이터베이스도 on은 있고 다 있는데 여기서 어디에 조건을 걸어야 되나요? and wr_10='on'해도 안되고 a.wr_10 , b.wr_10, c.wr_10다 컬럼이어디있다고 못찾아요...
