I have a database server with some databases. A few people have "ALL PRIVILEGES" on all databases. Now I am making online elections website for the students in my school and some of the people who have all privileges on all databases are taking part in the elections so "theoratically" they *could* modify the results...
Now I am wondering, is there any way to modify the privileges of these certain people so that they keep all privilegs on all databases except this single database without needing to modify there privileges on each database?

Thanks in advance!
