ROW_NUMBER() OVER tells DB2 how you want the rows numbered. If you are selecting Employee data, telling it to ROW_NUMBER() OVER (ORDER BY SALARY DESC) would have the row with the highest SALARY as #1, the second highest as #2, etc.
Select the exact same data with ROW_NUMBER() OVER (ORDER BY LASTNAME) would have a person with a LASTNAME starting with 'A' as #1 and someone with 'Z' as the very last.
