Can a cursor in DB2 be used to traverse a result set in reverse order? If so, how?

- Yes, by setting the SCROLL option to REVERSE
- Yes, by specifying the FETCH FIRST clause
- Yes, by using the FETCH PRIOR clause
Yes, a cursor in DB2 can be used to traverse a result set in reverse order by using the FETCH PRIOR clause. This clause allows the cursor to move backward through the result set, fetching the previous row relative to the current position. By specifying FETCH PRIOR, developers can implement functionalities such as scrolling through data in reverse chronological order or navigating through the result set in a custom manner. This capability enhances the flexibility and usability of DB2 cursors in various application scenarios.
