Answer:
SELECT inventory_id, film_id, title, store_id, address_id
FROM Inventory.Inventory
JOIN Business.store ON Inventory.store_id = store.store_id
JOIN Business.rental ON rental.film_id = Inventory.film_id
JOIN film_text ON Inventory.film_id = film_text.film_id
WHERE COUNT(rental_id) = 0;
Explanation:
The JOIN clause is also used to query tables from two databases. The Inventory and the Business database are joined in the inventory and store table respectively. The Query also joins the inventory table and the film_text table to get the title or name of the film rented where the rental_id count is equal to zero.
