MAX(salary) AS second_highest_salary
FROM (
SELECT
department,
salary,
ROW_NUMBER() OVER (PARTITION BY department ORDER BY salary DESC) as rn
FROM employees
) ranked
WHERE rn = 2
GROUP BY department;
I used a subquery with ROW_NUMBER() window function partitioned by department to rank salaries in descending order within each department. The outer query then filters for rank 2 (second highest) and groups to get distinct departments. This demonstrates mastery of window functions, which are essential for advanced analytics and ranking problems.
