I'm havng trouble getting my head around converting this to a count query for doing a pager_query.

SELECT c.name, c.mail, COUNT(*) AS num, pv.value AS usertype, td.name AS role FROM {comments} c INNER JOIN {node} n ON n.nid=c.nid INNER JOIN {term_node} tn ON tn.nid=n.nid AND tn.vid=n.vid INNER JOIN {term_data} td ON td.tid=tn.tid AND td.vid = 2 LEFT JOIN {profile_values} pv ON pv.uid=c.uid AND pv.fid = 13 WHERE c.mail <> '' GROUP BY role, c.mail ORDER BY num DESC

You can almost always do: SELECT COUNT(*) as expression FROM (SELECT ...); Drop the ORDER BY and any fields that you don't need from the query (you need the group by fields) and you'll be okay.
