public List demoSql(Integer cellId,Integer pageNum) {

        Sql sql = Sqls.create("SELECT  a.*,b.code FROM `tbl_cell_process_log` as a, tbl_cell as b where a.cell_id=@id and a.cell_id=b.idtbl_cell ORDER BY a.create_time desc");
        sql.params().set("id", cellId);
        final JSONArray json = new JSONArray();

                return json;
            }

        });

        dao().execute(sql);
        return sql.getList(String.class);
        // Nutz内置了大量回调, 请查看Sqls.callback的属性

        Sql sql = Sqls.create("SELECT  a.*,b.code FROM `tbl_cell_process_log` as a, tbl_cell as b where a.cell_id=@id and a.cell_id=b.idtbl_cell ORDER BY a.create_time desc");
        sql.params().set("id", cellId);
        Pager pager = new Pager(pageNum);
        sql.setPager(pager);
        sql.setCallback(Sqls.callback.maps());

        dao().execute(sql);
        List<Map> maps = sql.getList(Map.class);
        return new QueryResult(maps, pager);
