9) GRANT/REVOKE rights GRANTED BY specified user
(Alex Peshkoff)
Function:
Makes it possible to specify non-default (which is CURRENT_USER) grantor in GRANT and REVOKE
commands.
Syntax:
grant <right> to <object> [ { granted by | as } [ user ] <username> ]
revoke <right> from <object> [ { granted by | as } [ user ] <username> ]
Example (as SYSDBA):
create role r1;
grant r1 to user1 with admin option;
grant r1 to public granted by user1;
(in isql)
show grant;
/* Grant permissions for this database */
GRANT R1 TO PUBLIC GRANTED BY USER1
GRANT R1 TO USER1 WITH ADMIN OPTION
Misc:
GRANTED BY form of clause is recommended by SQL standard. AS is supported by some other
servers (Informix), and is added for better compatibility.
