Question

请考虑以下代码：

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);

Oracle程序：

  ICART_SESSION VARCHAR2(200);
  IEVENT_ID NUMBER;

    IFLASH_SEAT_STATUS_KEY => IFLASH_SEAT_STATUS_KEY
  );
  DBMS_OUTPUT.PUT_LINE('IRESULT = ' || IRESULT);
END;

我收到了错误消息：

为什么？网络搜索后，我找不到很多有用的信息..
我使用以下内容：
Oracle，版本：Oracle Database 11g第11.1.0.0.0版 - 生产

IRESULT是一个OUT参数，所以你应该这样注册：

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.registerOutParameter(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);

从Hibernate Native查询调用Oracle存储过程时出错
