I need to grab the max value of all of the data in a table grabbing
the max total for each client.  Example.

T1
id        total      clientid
1          100           111
2          200           111
3          100           112
4          150           112

I need a query that will grab the highest total per clientid (200, and
150) then average them.  My first inclination is to do a subselect

select avg(total) from t1 where t1.total=(select max(total) from t1 t2
where t2.clientid=t1.clientid)

CREATE TEMPORARY TABLE tmp SELECT MAX(total) AS total FROM T1 GROUP BY clientid;
SELECT AVG(total) FROM tmp;


But can't use subselects with mysql....how do I do it??

Sure you can... with the right version.
