Title: How to Revoke Permissions on an Object in Microsoft SQL Server 2000

Objective: The objective of this demo is to teach you the process of revoking permissions on an object in Microsoft SQL Server 2000. You can revoke a permission that has been granted or denied previously. Revoking is similar to denying in that both remove a granted permission at the same level. However, although revoking a permission removes a granted permission, it does not prevent the user, group, or role from inheriting a granted permission from a higher level. Therefore, if you revoke permission for a user to view a table, you do not necessarily prevent the user from viewing the table because permission to view the table was granted to a role to which he belongs.
