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 GRANT permission on both tables - 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, how to do this? ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
