Re: HASH JOINS -- PLEASE HELP ME

RTFM - http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14211/optimops.htm#sthref1394

You can set large hash_area_size and use parallel query. The best way to speed it up is to avoid it if nested loop does a better job.

But before you get into details of this I suggest something like:

Or even old but good one:

If you can't get those. Look at least at http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14211/toc.htm

And you don't need ALL CAPS - our monitors are pretty good to read it non-capitalized. ;-)
