 String sql = "select id, name, status from o_customer order by name desc";

 DB.sqlQuery(sql)
   .findEachRow((resultSet, rowNum) -> {

     // read directly from ResultSet

     long id = resultSet.getLong(1);
     String name = resultSet.getString(2);

     // do something interesting with the data

   });
