Hi Gurus,
Could someone shed some light on the following tkprof output.
To get 0 record it is aking more than 11 seconds. Also I see huge difference
between CPU time and elapsed time even though the system is not so busy(It is a
test machine. very low load on it). If you say it is waiting on something, could
you tell me how to identify the wait event associated with this and how to
rectify the same?
Also please let me know why the query count is very high?

and p.business_country_id in ( select countryabbrev from c )
