How to “subtract” privileges in MySQL

Question

I want to revoke update privielges from 2 columns of table \"transact\". I want the user to have all access to all other tables and data.

mysql> REVOKE UP         


        

Answer 1

Firstly - remove all privileges (on database, table, column levels).

1. Grant UPDATE (...and other) privileges to EACH table, except 'transact'.
2. Grant UPDATE privilege to specified fields in table 'transact'.
