Tre modi per archiviare i tuoi dati

Colonne nella tabella address

1) Crea una nuova tabella

CREATE TABLE zip_distance (
    postal_code INT,
    distance FLOAT
);

2) Inserisci dati nella tabella

INSERT INTO zip_distance (postal_code, distance)
VALUES
(53182, 3.4),                
(15540, 10.2),                
(67912, 1.9);


SELECT film_id, title
FROM film
WHERE rating = 'G';

CREATE TABLE family_films AS
SELECT film_id, title
FROM film
WHERE rating = 'G';

CREATE VIEW family_films AS
SELECT film_id, title
FROM film
WHERE rating = 'G';
