Can root use views created by non-existent users?

Question

MySQL

Manually make a request to create a view in MySQL. Specify a non-existent user as the view definer. The database quietly swallows this and displays only a warning that the user does not exist. At the same time, the view creates.
Question: will root be able to use this view? And flowing from it. Will other users with view execution rights be able to use a view created by a non-existent user (created via a specific database query)?

Answer 1

I always had problems because of this, when a dump made on one server was deployed on another. I decided to always specify [email protected] as DEFINER, because this user is always there. Those. if DEFINER does not exist VIEW does not work. Even root won't be able to use.
