I have this SQL expression (from
http://www.pui.ch/phred/archives/2005/04/tags-database-schemas.html)
SELECT b.*
FROM tagmap bt, bookmark b, tag t
WHERE bt.tag_id = t.tag_id
AND (t.name IN ('bookmark', 'webservice', 'semweb'))
AND b.id = bt.bookmark_id
GROUP BY b.id
HAVING COUNT( b.id )=3
How to implement this "HAVING COUNT(b.id) = 3" in ORM?
