Comment (by Awais Qureshi): I have created a simple app to reproduce this issue. You can see three `github` checks are running and `django30` and `django32` are showing error. Since this feature was introduced in `django30`. This change is related with Added support for check constraints on MySQL 8.0.16+. [https://github.com/django/django/pull/11743] Sample project with long table name where `mysql8` and `django` is generating internal checks if model has PositiveIntegerField. Possible solution: In case of `makemigrations` trigger some error with max length or truncate the check name. In case of upgrading existing project from `mysql57` to `mysql80` show some valid error message during `migrate` command. -- Ticket URL: <https://code.djangoproject.com/ticket/33169#comment:12> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
