Hi List,

I have following sql that runs in 1 sec:

SELECT b.* FROM RF_BALANCE_T b, rf_security_by_dceid s WHERE
(s.award_number = 'ALL')

OR (b.award_number = s.award_number AND s.project_number = 'ALL')
OR (b.award_number = s.award_number AND b.project_number=
s.project_number AND s.task_number = 'ALL')
OR (b.award_number = s.award_number AND b.project_number=
s.project_number AND b.task_number = s.task_number)

However, when I try to count above query as following, it hangs. Does someone have any ideas?

SELECT count(b.award_number) FROM RF_BALANCE_T b, rf_security_by_dceid s WHERE
(s.award_number = 'ALL')

OR (b.award_number = s.award_number AND s.project_number = 'ALL')
OR (b.award_number = s.award_number AND b.project_number=
s.project_number AND s.task_number = 'ALL')
OR (b.award_number = s.award_number AND b.project_number=
s.project_number AND b.task_number = s.task_number)
