You can do it manually by deleting those files:

​

    src/Entity/Product.php

    src/Repository/ProductRepository.php

​

If you have generated CRUD for your Product entity, you must delete:

​

    src/Form/ProductType.php

    src/Controller/ProductController.php

    templates/product (the product folder)

​

If you are in production env, you must run php bin/console cache:clear to delete the cache.

​

Think before updating your database schema. To update, run php bin/console d:s:u --force - but be aware of the implications in a prod environment.
