🚀 go-pugleaf

  my code is here...

  int xxx;
  Database db = new Database();
  QueryDataSet query = new QueryDataSet();
  query.setQuery(new borland.sql.dataset.
                             QueryDescriptor(db, "select " + s + ".nextval
from dual",         null, false, Load.ALL));
  query.open();

  at this point...what must i do?query's result is a number.and i want to
put this number in xxx variable.

  xxx  = query's first column's value.

  thanks in advance...
