考虑以下代码：
String checkSeatQuery = "BEGIN USP_RESERVESEAT(IRESULT=>?, ICART_SESSION=>?, IEVENT_ID=>?, ISESSION_ID=>?, IPRICE_SCHEME_ID=>?, ISEAT_ID=>?, IBLOCK_ID=>?, INO_OF_SEAT=>?, IPOS=>?, ISOURCE=>?, IFLASH_SEAT_STATUS_KEY=>?); END;";
Query q = entityManager.createNativeQuery(checkSeatQuery);
q.setParameter(1, DataTypes.STRING); //value passed in: 1
q.setParameter(2, cartSessionId); //value passed in: BT71C49DD999300D33E70B69F0A43F3436
q.setParameter(3, tblEvent.getId()); //value passed in: 20
q.setParameter(4,null); //value passed in: null
q.setParameter(5, Integer.toString(tempTicket.getTblPriceSchemes().getId())); //value passed in: 366
q.setParameter(6, seatId); //value passed in: null
q.setParameter(7, blockId); //value passed in: null
q.setParameter(8, accumulatedSeat); //value passed in: 1
q.setParameter(9, pos); //value passed in: 1
q.setParameter(10, source); //value passed in: 1
q.setParameter(11, null); //value passed in: null
String outputs = (String) q.getResultList().get(0);
