将内连接本机查询转换为 jpql

Question

我有这个方法

@Query("select * from feed_tbl feed inner join view_tbl viewers on feed.id <> viewers.feed_id where viewers.user_id = :userId", nativeQuery = true)
fun findAll(@Param("userId") userId: Long): List<Feed>

实体： 用户， 饲料

view_tbl 是用户实体中的 JoinTable

Answer 1

你应该可以使用not in 构造：

select f from Feed f where f not in (
  select u.feeds from User u where u.id = :userId
) 

当然，您需要将 User 映射到 Feed 为 many-to-many
