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.

Example:

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