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. SUM adds all prices together, which doesn’t make sense here. AVG provides an average, and COUNT only tells how many product prices are listed.
