The INLIST INTERATOR takes a result set, and "interates" over that
result set returning a result set that matches the values of the
IN predicate.
This is documented, quite well, in the Oracle9i Documentation.

Hi, list.
I'm trying to find out what's eating my system. I found the query, and
explain'ed it. I've never seen an "in list iterator" before. Can anyone
tell me what that is???
Thanks!!
