Java JPQL构造函数忽略具有空值的行

我有以下声明：

@Query("SELECT "
        + "new com.app.model.RestaurantOrderPartial( "
            + "o.orderId, o.orderedAt, o.orderType, o.orderState, o.orderValue, o.deliveryPrice, o.deliveredBy, o.driver) "
        + "FROM Order o "
        + "WHERE o.restaurant.restaurantId = ?1 "
        + "AND o.orderedAt BETWEEN ?2 and ?3 "
        + "ORDER BY o.orderedAt DESC ")
List<RestaurantOrderPartial> getRestaurantOrdersCompressed(long restaurantId, LocalDateTime dateBeforePeriod, LocalDateTime now); //12 Month

感谢您的帮助。

如果希望在o.driver为null时提取它，则必须指定一个左外部联接；o.driver始终是一个内部联接，因此会从结果中过滤掉null值

试试类似的东西

"SELECT "
        + "new com.app.model.RestaurantOrderPartial( "
            + "o.orderId, o.orderedAt, o.orderType, o.orderState, o.orderValue, o.deliveryPrice, o.deliveredBy, driver) "
        + "FROM Order o LEFT OUTER JOIN o.driver driver"
        + "WHERE o.restaurant.restaurantId = ?1 "
        + "AND o.orderedAt BETWEEN ?2 and ?3 "
        + "ORDER BY o.orderedAt DESC ")

如果驱动程序为空，是否设置restaurantId和oderedAt？是。除o.driver.driver（在引用相应表中的驱动程序的列中的id）外，所有内容都已设置是否对数据库运行hibernate生成的查询，以确保返回的数据包含具有驱动程序值

null

的行，从而排除任何数据设置问题？
