ОШИБКА 1452 Mysql Forward Engineering

Я пытаюсь перенаправить инженер ERD, и я продолжаю получать следующее сообщение об ошибке. Я не совсем понимаю, что это значит, может кто-нибудь объяснить, где мне нужно искать проблему?ОШИБКА 1452 Mysql Forward Engineering

Выполнение SQL скрипт в сервере

ERROR: Error 1452: Cannot add or update a child row: a foreign key constraint fails (database . employee , CONSTRAINT fk_employee_department1 FOREIGN KEY (dpt_id) REFERENCES department (dpt_id) ON DELETE NO ACTION ON UPDATE NO ACTION)

SQL код:

INSERT INTO `database`.`employee` (`emp_id`, `dpt_id`, `emp_fname`, `emp_lname`, `emp_street`, `emp_city`, `emp_state`, `emp_zip`, `emp_phone`, `emp_email`, `emp_notes`) VALUES (NULL, 1, 'Harry', 'Potter', '4 Privet Drive', 'Tallahassee', 'Fl', '32304', '9544564567', '[email protected]', NULL)

SQL выполнение скрипта закончил: заявления: 32 удалось, 1 не удалось

Извлечение назад определения представлений в окончательном виде. не ничего принести

Это все сценарии, как я сказал, что я очень смущен и не знаю, где это исправить

вам нужно сначала вставить запись в deparment таблицу

employee таблица имеет внешний ключ для таблицы deparment, так как в таблице department нет записи для идентификатора 1, вставка не работает.

Также в вашей таблице department есть employee есть внешний ключ, который будет рекурсивным.

необходимо изменить структуру таблицы.

Строка ошибки ниже ясно говорит вам, в чем проблема. dpt_id на вашем Employee Таблица имеет отношение внешнего ключа с Department таблиц dpt_id column.

Итак, сначала необходимо вставить строку в таблицу Department, прежде чем вставлять тот же ключ в таблицу employee. Другими словами, тот же dpt_id должен существовать в таблице department, прежде чем вы сможете вставить этот ключ в любую ссылочную таблицу.

CONSTRAINT fk_employee_department1 FOREIGN KEY (dpt_id) REFERENCES department (dpt_id)
