我在Hibernate的AppointmentEntity实体中有一个名为mobileAdditionalDuration的Duration字段。在我的AppointmentRepository接口中，我试图编写一个SQL查询，从startTime和endTime字段中减去此持续时间，它们的类型为LocalTime。
下面是我写的查询：

@Query(
        value = """
            SELECT EXISTS (
                SELECT 
                    a.date, 
                    SUBTIME(a.startTime, a.mobileAdditionalDuration) as startTime1, 
                    SUBTIME(a.endTime, a.mobileAdditionalDuration) as endTime1 
                FROM appointment a 
                WHERE (a.date = ?1) AND ((startTime1 < ?2 AND endTime1 > ?2) OR (startTime1 < ?3 AND endTime1 > ?3))
        )
    """
    )
    fun checkIfAppointmentAlreadyExistAtThisTime(date: LocalDate, start: LocalTime, end: LocalTime): Boolean

然而，当我运行查询时，我得到了异常Could not interpret path expression 'aStartTime'。有人能帮助我纠正我的查询以获得所需的结果吗？
