Database lookup

[ewoweof]

Hi there,
I'm having some issues with a test database I'm trying to break into. I have already inserted a hidden user with admin privileges to try dumping the tables but got some fight with the default admin. Anyone knows how can I revoke the privileges from the original admin?

how much access do you have? can you do this query?
REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'username'@'host';
that's for mysql but it will depend on which database manager you are using
