Seema, your output doesn't make sense ... if you want top 10 by domain, why yahoo.com is listed multiple times? If you wat by domain try something like select * from (select trunc(date_col), domain, count(spam_msgs),=20 rank () over (order by count(spam_msgs) partition by trunc(date_col) r) from my_table group by trunc(date_col), domain) where r <=3D 10 / of course check for syntax ...
