Comments for Automatic Column Group Detection in Oracle Database 12c Release 1 (12.1)

Hello Tim,
is there a way to disable the automtic creation of column group statistics?
Thanks

There is a patch that back-ports the new control parameters from 12.2 to 12.1, which allows you to prevent them. Alternatively, set the equivalent underscore parameters. See:
