I have a query I'm having trouble with. If do this query which is DATE plus

SELECT e.zzk FROM exams e
-- JOIN Appt_ a ON e.IdAppt = a.IdAppt
-- JOIN Affil_ af ON a.IdAffil_primary = af.IdAffil
WHERE e.dateexam >= '2012-09-01' AND e.dateexam <= '2012-09-30'

Hi All,
I am using mysql 5.0.41, on debian, with 8 CPU, 8 GB RAM.
I am having the below query with explain plan
select * from (select * from (select truncate0.34*LOG(10,((NO_BIDS +
1)/(TOTAL_QTY
+ 1 + (0.24*LOG(10,100*( (SOLD_QTY + 1) / (TOTAL_QTY + 1 + 0.14*(1
/ LOG(10, 10 + TOTAL_Q
