Suppose we have table A and table B. When action is performed on table A
(for example INSERT), some action (for example UPDATE) through the trigger
is done on table B.
If user had permission on both tables (GRANT INSERT on table A and GRANT
UPDATE on table B)- everything is good. But in that way user can get access
to table B directly.
If I need to limit user's access to table B only through the trigger from
table A, how to do this?
