The following example provides a rank in descending order of employees' salaries in Utah and New York. Notice that the 7th and 8th employees have an identical salary and therefore share the 7th place ranking. The employee that follows receives the 9th place ranking, which leaves a gap in the ranking sequence (no 8th place ranking).

SELECT Surname, Salary, State,
RANK() OVER (ORDER BY Salary DESC) "Rank"
FROM GROUPO.Employees WHERE State IN ('NY','UT');
