Question

我有一个spring-boot应用程序并使用JPA与PostgreSQL交谈。我有自定义查询

SELECT * FROM public.user
INNER JOIN public.company
ON (public.user.company_id = public.company.id)
INNER JOIN public.truck
ON (public.user.id = public.truck.user_id)
INNER JOIN public.job
ON  (public.truck.id = public.job.truck_id)
WHERE public.company.id = 1
ORDER BY 1 USING < LIMIT 10 OFFSET 0

当我在SQL编辑器（如DBVisualizer或pgAdmin）中运行上述查询时，我收到订单，当我将其反转时

SELECT * FROM public.user
INNER JOIN public.company
ON (public.user.company_id = public.company.id)
INNER JOIN public.truck
ON (public.user.id = public.truck.user_id)
INNER JOIN public.job
ON  (public.truck.id = public.job.truck_id)
WHERE public.company.id = 1
ORDER BY 1 USING > LIMIT 10 OFFSET 0

我仍然得到了正确的结果，但是来自我的代码，就像

 @Query(nativeQuery = true, value = "SELECT * FROM public.user" +
        " INNER JOIN public.company" +
        " ON (public.user.company_id = public.company.id)" +
        " INNER JOIN public.truck" +
        " ON (public.user.id = public.truck.user_id)" +
        " INNER JOIN public.job" +
        " ON  (public.truck.id = public.job.truck_id)" +
        " WHERE public.company.id = :companyId" +
        " ORDER BY :columnNumber USING > LIMIT :pageSize OFFSET :offset")
List<Object[]> findJobsASC(@Param("companyId") Long companyId, @Param("pageSize") int pageSize, @Param("columnNumber") int columnNumber, @Param("offset") int offset);

 @Query(nativeQuery = true, value = "SELECT * FROM public.user" +
        " INNER JOIN public.company" +
        " ON (public.user.company_id = public.company.id)" +
        " INNER JOIN public.truck" +
        " ON (public.user.id = public.truck.user_id)" +
        " INNER JOIN public.job" +
        " ON  (public.truck.id = public.job.truck_id)" +
        " WHERE public.company.id = :companyId" +
        " ORDER BY :columnNumber USING < LIMIT :pageSize OFFSET :offset")
List<Object[]> findJobsDESC(@Param("companyId") Long companyId, @Param("pageSize") int pageSize, @Param("columnNumber") int columnNumber, @Param("offset") int offset);

companyId = 1，pageSize = 10，columnNumber = 1和offset = 0。

当我运行这两个函数时，我得到相同的结果，它没有被命令。我尝试过使用ASC和DESC但没有成功。我也尝试使用columnName代替columnNumber，但它仍然无法发挥作用。

我做错了什么？
