A alternativa Access mais citada para o MySQL
GROUP_CONCAT() função é ConcatRelated() de Allen Browne função, disponível aqui
. Quanto aos parênteses em torno de JOINs, sim, o Access SQL é exigente com eles. Ao invés de
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
experimentar
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
