    Description

      Currently if there are no stats hive bails out of cbo and try non-cbo route. Since most of the subqueries are only supported in CBO and not in non-cbo we end up with completely different error message. This creates confusion.
      One possible solution is to throw warnings that stats are missing before throwing subquery related error message.
