Hello, I'm trying to set up some rules and was following the examples in the
Programmer's guide form the docs, and it gives an example similar to this:
CREATE RULE log_shoelace AS ON UPDATE TO shoelace_data WHERE NEW.sl_avail != OLD.sl_avail
DO INSERT INTO shoelace_log VALUES ( NEW.sl_name, NEW.sl_avail,
getpgusername(). 'now'::text );
What I want to do is very similar:
CREATE RULE update_login AS ON UPDATE TO user_info WHERE NEW.login != OLD.login
DO UPDATE user_dept SET login = NEW.login WHERE login = OLD.login;
I get an error:
"ERROR: Table old does not exist."
What's going on?
Also, the docs say you can do multiple actions in a rule... what is the syntax?
I tried putting the actions in parens separated by semicolons or commas wit
no luck...
There wasn't an example in the docs that did more than on action.
Thanks, Doug.
