Tutorial provided by google only show extract 1 field only. how can i extract/query more than 1 field. please help.
Attached code from stockwatcher at server side (StockServiceImpl): - public String[] getStocks() throws NotLoggedInException { checkLoggedIn(); PersistenceManager pm = getPersistenceManager(); List<String> symbols = new ArrayList<String>(); try { Query q = pm.newQuery(Stock.class, "user == u"); q.declareParameters("com.google.appengine.api.users.User u"); q.setOrdering("createDate"); List<Stock> stocks = (List<Stock>) q.execute(getUser()); for (Stock stock : stocks) { symbols.add(stock.getSymbol()); } } finally { pm.close(); } return (String[]) symbols.toArray(new String[0]); } its clearly the code only extract 1 field. how to extract another field..
