I would like to know if I can request a Mysql database created before I create my Django project with Django ORM. For instance, is it possible to run that request with that database : User.objects.all(). In this case, “User” is a table of my database.
You can use a MySQL database, yes.
See this link for supported databases.
Be aware that MySQL databases often are case insensitive, so you might have to ensure you have a CS collation or using a _bin Character set. See more here.
