Home -> Community -> Mailing Lists -> Oracle-L -> RE: Oracle CBO question
It's funny how sometimes on Oracle-L the answers to a question like this
comes before the actual question!! :-) Often I'm like... ok, what was the
question?
Cheers and happy 4th!!

I have received a question from a consultant developer - below. Can
anyone answer?
I was once told that the CBO can only handle a certain number of tables in a query (16 iirc). Do you know what the CBO does when there are more? Try to optimize based on knowledge of the first 16 tables in the Where clause?
