Возникла проблема во внешнем ключе при создании таблицы с mysql верстаком.
Когда я создаю таблицу с mysql верстаком, верстак выдает мне эту ошибку:
Выполнение сценария SQL на сервере. ОШИБКА: Ошибка 1005: Невозможно создать таблицу kipit. unlike_game_library (ошибка: 150 "Неправильно сформировано ограничение внешнего ключа")
Executing SQL script in server
ERROR: Error 1005: Can't create table `kipit`.`unlike_game_library` (errno: 150 "Foreign key constraint is incorrectly formed")

Я проверяю тот же тип, настройку юникода и уникальный ключ, но это не работает
