Remember the task from the third section, where you calculated the maximum price of a Diesel car? What if we want to see not only the price, but also what model, mileage, and other characteristics of this car?

One of the ways to solve it - is using nested queries, but this is not the topic for this course. Easier, you can order your table in descending order and limit the number of rows to 1! For example,

SELECT *
FROM audi_cars
WHERE fueltype = 'Diesel'
ORDER BY price DESC
LIMIT 1

This query will return all the Diesel cars, ordered by price in descending order with only 1 row! This is the car we were looking for.
