Hi all,
I know this is RTFM but I can't find the right part in the FM to R. So any help would be appreciated:
In the context of:
DBMS_STATS.GATHER_DATABASE_STATS(method_opt=>'FOR ALL HIDDEN COLUMNS');
what is a "hidden column". I tried gathering stats FOR ALL HIDDEN COLUMNS and it didn't seem to gather any stats for any columns. What is it meant to do?
