-- • Создайте две таблицы: people и people_log. Первая таблица должна
|
||||
-- содержать поля идентификатор (id), имя (first_name), фамилия
|
||||
-- (last_name), дата рождения (birthday), текущее состояние счёта
|
||||
-- (amount). Поле id – это первичный ключ. Поле amount – это
|
||||
-- действительное число. Вторая таблица должна содержать поля:
|
||||
-- идентификатор человека (person_id) дата операции (operation_date),
|
||||
-- сумма (sum). Поле person_id должно быть ограничено, как внешний
|
||||
-- ключ, ссылающийся на поле id таблицы people. Поле operation_date
|
||||
-- должно позволить сохранять дату и время. Поле sum – это
|
||||
-- действительное число. Заполните таблицы people и people_log

-- несколькими записями (не менее 5 на таблицу).
