Удаление связанных данных
29.09.2014, 07:53. Показов 1055. Ответов 0
Здравствуйте. Недавно начал изучать php, чуть позже пришлось углубляться в изучении баз данных. Есть необходимость в следующем: есть 3 таблицы - user, profile, access. В первой, есть след.колонки login, email , pass , profile (FK на табл.profile по id) , access (FK на табл.access по id). Соответственно с помощью php-кода я успешно добавляю записи в данные таблицы. После чего допустим напрямую из Mysql Workbrench хочу сделать truncate таблицы user, после чего ожидаю что связанные данные, будут так же удалены из двух других таблиц, но это не происходит. Как правильно организовать эту связь на уровне СУБД?
P.s. через alter table таблицы user указал действия при обновлении и удалении строк на cascade.

Сделал дамп базы, дабы заодно показать всю структуру базы:
