Question

При попытке добавить внешний ключ вылетела ошибка

До этого были произведены следующие действия (Действовал согласно https://folkprog.net/sozdanie-svyazey-phpmyadmin/.)

Запрос на создание FK - Error text:

ALTER TABLE monoblocks ADD FOREIGN KEY (image_id) REFERENCES monoblock_images(id) ON DELETE RESTRICT ON UPDATE RESTRICT;

#1452 - Cannot add or update a child row: a foreign key constraint fails (myishop.#sql-2150_93, CONSTRAINT #sql-2150_93_ibfk_21 FOREIGN KEY (image_id) REFERENCES monoblock_images (id))

Пытался выполнить SHOW CREATE TABLE monoblocks и получил следующий результат (в sql новичок - поэтому не серчайте)

Нашел

Содержимое таблицы monoblocks следующее

Каким образом можно отредактировать image_id в monoblocks?
