The NTILE function divides a set of ordered rows into equally sized buckets and
assigns a bucket number to each row.
Useful for calculating tertiles, quartiles, quintiles, etc.

SELECT last_name, salary,
NTILE(4) OVER (ORDER BY salary DESC) AS quartile
FROM employees
WHERE department_id = 100;
{code}
