SELECT * FROM (SELECT uid, count(uid) AS count1 FROM triangulated WHERE uid != 'anonymus' AND uid != 'anonymous' AND uid != '' GROUP BY uid) AS c1 LEFT JOIN (SELECT uid, count(uid) AS count2 FROM points WHERE uid != 'anonymus' AND uid != 'anonymous' AND uid != '' GROUP BY uid) AS c2 ORDER BY count1 DESC LIMIT 10; (Apologies for syntax errors, if any - I haven't tried it out,) I used LEFT JOIN because you are ordering by count1, so you probably won't want any rows where count1 is null. If the total of rows from subselect c1 was likely to be less than 10, you might want to do a FULL JOIN and order by count1, count2. -- Oliver Elphick [EMAIL PROTECTED] Isle of Wight, UK http://www.lfix.co.uk/oliver GPG: 1024D/3E1D0C1C: CA12 09E0 E8D5 8870 5839 932A 614D 4C34 3E1D 0C1C ======================================== "But be ye doers of the word, and not hearers only, deceiving your own selves."
