Here's a scheme for query optimization that probably needs to be
avoided in that it would run afoul of a patent held by Oracle...


It looks like what they have patented is pretty much a "greedy search"
heuristic, starting by finding the table in a join that has the
greatest selectivity (e.g. - where the number of entries selected is
cut the most by the selection criteria), and then describes how to
search for the "best" approach to joining in the other tables.
output = reverse("gro.mca" "@" "enworbbc")
"If I  could find  a way to  get [Saddam  Hussein] out of  there, even
putting a  contract out on him,  if the CIA  still did that sort  of a
thing, assuming it ever did, I would be for it."  -- Richard M. Nixon
