ORA-14134: indexes cannot use both DESC and REVERSE

ORA-14134: indexes cannot use both DESC and REVERSE

Cause: An attempt was made to make a reverse index with some index columns marked DESC.

Action: Do not use DESC in reverse indexes. The rule-based optimizer can scan indexes backwards, which allows a normal reverse index to simulate a reverse index with columns marked DESC.
