SQL interview exercise on Joins, difficulty 1 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
Show every order line with its product's name. Columns: order_id, product, quantity. Sorted by order_id, then product.
