查询最近有文章更新的文章分类名称SQL
有文章分类表和文章表两个表，表结构分别是：

Article
Id CategoryId Title LastUpdatedTime（文章最后更新时间）

Category
Id CategoryName

需要查询出 最近有文章更新的10个 CategoryName

请教大家SQL语句该怎么写？ 数据库是SQL Server，谢谢！
[最优解释]
select categoryname from category where id in (select top 10 categoryid from article group by categoryid
order by max(LastUpdatedTime) desc)
[其他解释]

select * from Category where id in
(
select top 10 CategoryId  from Article group by CategoryId order by LastUpdatedTime desc
)
