Het meest geciteerde Access-alternatief voor de MySQL GROUP_CONCAT()

Wat betreft haakjes rond JOINs, ja, Access SQL is daar kieskeurig over. In plaats van
FROM
actor AS a
LEFT JOIN film_actor AS fa ON a.actor_id = fa.actor_id
LEFT JOIN film_category AS fc ON fa.film_id = fc.film_id
LEFT JOIN category AS c ON fc.category_id = c.category_id
probeer
FROM
(
(
actor AS a
LEFT JOIN
film_actor AS fa
ON a.actor_id = fa.actor_id
)
LEFT JOIN
film_category AS fc
ON fa.film_id = fc.film_id
)
LEFT JOIN
category AS c
ON fc.category_id = c.category_id
