Re: Having One and Only User But Having Not Admin Permissions

[Barry Galbraith]

By default, root user has all privileges, including the ability to GRANT privileges to other users. Other users can only GRANT privileges if root user has GRANTed them the GRANT OPTION.

The bottom line.
Use root to run mysqldump.
Or, login as root and GRANT PROCESS privilege to 'Mike'
Be aware, PROCESS is a global privilege, so root will need to do something like this
GRANT PROCESS on *.* to 'Mike'@'%';

Good luck,
Barry.
