Hello Tim! Two questions: 1) Why doesn't Oracle calculate complete information for Data Guide when creating an index? For complete statistics, you run the separate command - Is this the case when you can't fully count on automatic statistics gathering? 2) Can we index virtual columns after I believe here the rules are the same as for regular virtual columns.
