I ran into the same problem. I don't know exactly why. - Have you tried the SAMPLE option? When I was having the same problem, I tried sampling 10% - my dba class instructor said that was pretty reliable.
- but it depends on the version of oracle that you're using. do not even attempt this under 7.0, wait till 7.2 at least. - what i did for my extremely large tables was take a sample table myself. create table sub_large as select * from large where rownum <= (type 1/100th of the number of rows) then multiply the results by 100.
kludgy but it works.
