At first glance, I'd guess this is much more CPU intensive than the
table comparison technique Tom Kyte pointed out at
http://www.oracle.com/technology/oramag/oracle/05-jan/o15asktom.html
Both techniques would full-scan the tables, but the HASH_VALUE would
have plenty of SQL to PL/SQL context switches. Of course, this is
merely an opinion, and I'd certainly be interested in the results (may
have to try this one on my own, later tonight.)
