Sybase 12.4.2 manual Deleting views, Views in the system tables, 131

CHAPTER 3 Working with Database Objects

•The user was granted appropriate permission(s) for the operation on the view by a non-DBA user. This user must be either the owner of the view or have WITH GRANT OPTION of the appropriate permission(s) on the view. The owner of the view must be either:

•a DBA, or

•a non-DBA, but also the owner of all the base table(s) referred to by the view, or

•a non-DBA, and not the owner of some or all of the base table(s) referred to by the view, but the view owner has SELECT permission WITH GRANT OPTION on the base table(s) not owned and any other required permission(s) WITH GRANT OPTION on the base table(s) not owned for the operation.

Instead of the owner having permission(s) WITH GRANT OPTION on the base table(s), permission(s) may have been granted to PUBLIC. This includes SELECT permission on system tables.

UPDATE permissions can be granted only on an entire view. Unlike tables,

UPDATE permissions cannot be granted on individual columns within a view.
