hql 多对多查询 elements

可编写如下Hql 语句完成查询：

select Blog 
from Blog, Book
where Blog.author in elements(Book.authors)
	and Book.id=?

对应的Sql近似如下：

select
 blog.*
from
 blog, book
where
 (blog.author 
in
 (
select
 author.authorid
        from
 book_author
        where
 book.id=book_author.bookid))
    and
 book.id=?
