# That is a very little advertised feature of the 11G version.
If curious about 12c hunt down Maria's presentation on new stuff in the optimizer.
A whole bunch of new stuff is going to be jumping in ... including switching execution plans in flight ( think just nested join over to hash join in first release of 12c ). Also optimizer can create extended statistics on the fly ( between columns ) even when you do not generate them explicitly.
Lots of learning in store for the 12c optimizer and statistics! Received on Thu Oct 11 2012 - 21:26:40 CEST
