Обсуждение: Authorized privileges when calling a procedure

Hi,

I have another question. It appears that when you create a procedure and grant access on it to another user, the user must have privileges to all objects that the procedure references. Can someone confirm this, and is there a way to change the privilege authorization to the user that defined the procedure?

Thanks in advance,

Jed S. Walker

Mark the function as SECURITY DEFINER --- this is like setuid programs
in Unix.

(No, it's not a very intuitive label for the behavior, but it's what
the SQL spec says to use.)

Great, that's exactly what I need.

Thanks!
