Subj:   Re: SQL Tuning - Spool Space Problem
 
From:   Carmen Hofmann

I think the only problem is the DISTINCT-expression. We generally don't use DISTINCT because of spool problems. Try to replace it by a GROUP-BY-clause in combination with a derived table:

select count(*) from
(select a.ban
from jq8274.bill_charge a, jq8274.bill_adjustment b, jq8274.tax c
where a.ban = b.ban
and a.ban = c.ban
group by a.ban) derived (aban)
;

Hope that helps, Carmen.
