A retаil cоmpаny’s dаtabase has a prоducts table with a cоlumn called price. The CEO asks: What’s the highest price of any product we sell? Which SQL query answers that? SELECT SUM(price) FROM products SELECT MAX(price) FROM products SELECT AVG(price) FROM products SELECT COUNT(price) FROM products Answer: SELECT MAX(price) FROM products Explanation: MAX retrieves the largest single value from the column.
