Subject: Question on rule
Date: Sat, 21 Feb 2009 09:43:35 +0100
Message-ID: <200902210943.35832@zmi.at> (raw)

I have a question to creating a rule:

CREATE RULE dbmail_mailboxes_autocreate AS ON INSERT TO dbmail_users DO 
ALSO insert into dbmail_mailboxes (owner_idnr,name) values 
(NEW.user_idnr,'INBOX'),  (NEW.user_idnr,'Gesendete Objekte'), 
(NEW.user_idnr,'Entwürfe'), (NEW.user_idnr,'Junk'), 
(NEW.user_idnr,'Papierkorb');
ERROR:  VALUES must not contain OLD or NEW references
TIP:  Use SELECT ... UNION ALL ... instead.

But in http://www.postgresql.org/docs/8.3/interactive/rules-update.html 
the examples also use NEW in the values. Or can I only use a rule within 
the same table?

If I need to use a TRIGGER: I tried with creating a function, but I 
don't know how to pass the current user_idnr to that function from the 
trigger. I managed to create the function:

CREATE FUNCTION dbmail_mailboxes_autocreate_function(user_idnr bigint) 
returns integer AS $$ BEGIN insert into dbmail_mailboxes 
(owner_idnr,name) values (user_idnr,'INBOX'), (user_idnr,'Gesendete 
Objekte'), (user_idnr,'Entwürfe'), (user_idnr,'Junk'), 
(user_idnr,'Papierkorb'); END; $$ LANGUAGE plpgSQL;

But I don't know how to do the trigger. Can someone help me?
