Sakila is a sample database provided by MySQL, meant to be used in tests and documentation examples. This page lists some example queries against that database.

Get a non-normalized selection of actors and films in which they played:

SELECT  actor.first_name, 
        actor.last_name, 
        film.title 
FROM actor, film, film_actor 
WHERE film_actor.actor_id = actor.actor_id 
AND film_actor.film_id = film.film_id;

Get the same result with double INNER JOIN:

SELECT actor.first_name, actor.last_name, film.title 
FROM film_actor 
INNER JOIN actor ON film_actor.actor_id = actor.actor_id 
INNER JOIN film ON film_actor.film_id = film.film_id;

Example script:

mysql   --silent \
        --skip-column-names \
        --user mysqldumper \
        --execute 'SELECT User, Host from mysql.user' | \
        while read User Host; do 
            mysql --user mysqldumper --execute "SHOW GRANTS FOR '$User'@'$Host'"; 
            echo "==========================="; 
        done

The mysqldumper user only requires read permissions on the databases.
