Question

/* name - "Slim", type - "Giraffe", country_id - 1 */
INSERT INTO Animals (name, type, country_id) VALUES ('Slim', 'Giraffe', 1);

SELECT name, type , country FROM Animals INNER JOIN Countries ON Animals.country_id = Countries.id GROUP BY name, type, country ORDER BY country

Answer 1

The task just doesn't ask for it. The task is to list all animals, not groups of them.

Answer 2

Try without the GROUP BY clause.

Answer 3

Thx. why is Group By not used? AVG
