Example 1: User1 creates table1, and user2 creates view2 on table1
- User1 can always access table1, since user1 is the owner.
- User1 can always access table1 through view2, since user1 is the owner of the underlying table. This is true even if user2
does not grant permission on view2 to user1.
- User2 can access table1 directly or through view2 if user1 grants permission on table1 to user2.
- User3 can access table1 if user1 grants permission on table1 to user3.
- User3 can access table1 through view2 if user1 grants permission on table1 to user2 with grant option and user2 grants permission on view2 to user3.
