Sql Postgres的顺序是两次描述，然后是ASC

我有一个递归查询

With RECURSIVE tree AS
 (
 SELECT * FROM comments WHERE id = 83
 UNION
 SELECT t.*
      From comments t
 JOIN tree rt ON rt.parent_id = t.id

 )
 SELECT * from tree ORDER BY id DESC LIMIT 5

我如何通过ASC再订购一次

Edit1:尝试了此解决方案：

给我一个错误：

ERROR:  subquery in FROM must have an alias 

---

在PostgreSQL中，所有表表达式（在中的

之后选择）都需要命名。也就是说，他们需要有一个别名。只需添加任何别名。例如，我添加了
x
，如：

With RECURSIVE tree AS
 (
 SELECT * FROM comments WHERE id = 83
 UNION
 SELECT t.*
      From comments t
 JOIN tree rt ON rt.parent_id = t.id

 )
 select * from (SELECT * from tree ORDER BY id DESC LIMIT 5) x order by id 

你发现了吗？
你能解释一下所需的顺序吗？我尝试了那个解决方案，但它不起作用，这就是我为什么发帖的原因。错误：FROM中的子查询必须有别名谢谢你指出了这一点
select * from (SELECT * from tree ORDER BY comment_id DESC LIMIT 5) t order by comment_id    

With RECURSIVE tree AS
 (
 SELECT * FROM comments WHERE id = 83
 UNION
 SELECT t.*
      From comments t
 JOIN tree rt ON rt.parent_id = t.id

 )
 select * from (SELECT * from tree ORDER BY id DESC LIMIT 5) x order by id
