Как получить sys_refcursor в таблицу ассоциативного массива в PL/SQL

Используя почти тот же код, который я использовал при ответе на другой ваш другой сообщения, он берет продукты, которые возвращаются вашей функцией, и сохраняет значения в коллекцию.

Пожалуйста, дайте мне знать, если вам нужны разъяснения или у вас есть другие вопросы относительно моего ответа здесь.
