Revoking Permissions on a Table

Remove table permissions from users and roles.

Prerequisites
Database Version Database Object Privileges
SAP Sybase IQ 15.3 and 15.4 You must have one of:
  • DBA authority
  • PERMS ADMIN authority
  • You have administrative rights (with grant option) to the permission
  • You own the database object
SAP Sybase IQ 16.0 You must have one of:
  • MANAGE ANY OBJECT PRIVILEGE system privilege
  • You have administrative rights (with grant option) to the permission
  • You own the database object
Task

The REVOKE command applies to the database object permission itself, not to any administrative right granted on the permission. Therefore, to remove the administrative right only and leave the database object permission intact, do not use the Revoke button. Rather, regrant the specific permission without administrative rights. Only the original grantor can remove the administrative rights only from a granted permission. If another grantor regrants the same permission without administrative rights, a new permission without administrative rights is granted, but the original permission with administrative rights remains and takes precedence over any other non-administrative grants of the same permission to the same user or role.

If multiple permissions are granted, you can revoke some or all of the permissions. However, if you revoke a permission granted administrative rights, and the grantee has granted the permission to other users, who in turn have granted it to other users, and so on, every grantee in the chain who has received the permission indirectly, with or without administrative rights, also has their permission revoked. For example, UserA is granted the SELECT permission with the With grant option. UserA grants SELECT to UserB with the With grant option. UserB grants SELECT to UserC and UserD without administrative rights and to UserE with administrative rights. When you revoke the SELECT permission from UserA, it is also revoked for UserB, UserC, UserD and UserE.
