For whatever reason i thought that CBO will be used if ALL tables have
statistics collected for them, but it seems it's the other way around,
if at least ONE table in the query has statistics for it it would be
the other way around, could somebody confirm?
We have some tables that stay empty, and get filled very quickly and
get used right away, and i hoped to avoid FTS by deleting statistics
for those, and relying on RBO, now i need to come up with a better
strategy.

We use Oracle 8.1.7.4 on Solaris 2.7 boxes
