SQL Query to Rank Rows

Assign rankings using ROW_NUMBER, RANK, or DENSE_RANK window functions.

Quick Answer

SELECT name, salary, RANK() OVER (ORDER BY salary DESC) as rank FROM employees;

Explanation

ROW_NUMBER gives unique sequential numbers. RANK gives same rank to ties but skips numbers. DENSE_RANK gives same rank but doesn't skip.
