Projections With Expressions and Statistics

Is it possible to have projections with expressions and those projections have full statistics?  From what I can tell these only have ROWCOUNT statistics.


I have a handful of these projections where I'm converting numeric source data into DATE and TIMESTAMP data types on load.  However, I'm not getting the performance lift that I would expect by querying these projections instead of the anchor table.  My explain plan shows NO STATISTICS for each join and I would think that's playing a role in the lackluster query performance.


Any advice is welcomed, thanks.
