执行查询时出现错误。错误是：

java.lang.IllegalArgumentException：org.hibernate.hql.internal.ast.QuerySyntaxException：意外令牌：在第 1 行附近开始，第 84 列 [来自 com.services.om.entity.OrderLines，其中 orderNumber in (:order_Numbers) 以 parentLineIdentifier 开头null 通过先前 orderLineIdentifier = parentLineIdentifier 连接]

我的 DAO 代码是：

public List<OrderLineVO> findAllOrders(List<BigDecimal>  orderNumbers) throws OrderManagementException {
        try{

            String getAllOrders = "from OrderLines where orderNumber in (:order_Numbers) order by orderDate desc ";

            Query query = em.createQuery(getAllOrders,OrderLines.class);
            query.setParameter("order_Numbers", orderNumbers);
            List<OrderLines>  orderLinesList = query.getResultList();


            String queryParentChild = "from OrderLines where orderNumber in (:order_Numbers) start with parentLineIdentifier is null connect by prior orderLineIdentifier = parentLineIdentifier";
                        Query queryParent = em.createQuery(queryParentChild, OrderLines.class);
            queryParent.setParameter("order_Numbers", orderNumbers);

            List<OrderLines>  orderLinesList2 = queryParent.getResultList();

            return OrderLineUTIL.getOrderLines(orderLinesList);
        }catch(Exception exception){
            logger.error(exception.getMessage());
            throw new OrderManagementException(exception.getMessage());
        }
    }

em.createQuery(queryParentChild, OrderLines.class); // Line is giving above error.

有什么建议吗？

实体类字段变量也在查询中正确标记。
