I want to execute such sql:

update blog_entry set comment_number = (select count(*) from
blog_comment where blog_comment.root = blog_entry.id)

How I can write such query in DQL? I tried:

        $q = Doctrine_Query::create()
            ->update('Blog_Entry Entry')
            ->set('Entry.comment_number', '(SELECT COUNT(Comment.id)
FROM Entry.Blog_Comment Comment WHERE Comment.root = Entry.id)')
            ->execute()
        ;

but it throws exception "Unknown component alias Comment".

http://www.doctrine-project.org/documentation/manual/1_1/en/dql-doctr...
only report subquery support in FROM, SELECT, and WHERE statements.
Maybe it just plain doesn't work in SET, yet?

May be, I thought there are some core developers who have to know
this :)

Anyway, parseDqlQuery does it for me, but I can not find any
documentation about this method except API. I tried online docs, but
actually there is no good search. And PDF version is not avaiable (I
tried http://www.doctrine-project.org/documentation/manual/1_1/en/pdf
) . Can someone give me link to parseDqlQuery documentation or it's
prefered to use Doctrine_RawSql instead?
