Imagine that I run this command:
GRANT ALL PRIVILEGES ON *.* TO 'user'@'host';
Now in every new DB, the user has full access. The question is, imagine that at some point I want that those . privileges don't apply to new databases. Is that possible?
I just thought about erasing user and GRANT privileges to the last db's created but it could be quite hard if there are a lot of them... and I wondered if there was a "REVOKE from now on ..." hidden from google command.
