Обсуждение: Question on Rules
I am creating a rule which will copy a record when it is changed to a
audittable. My question is that the first column is a UUID data type
with a defined as auditaccessorid uuid DEFAULT
isscontrib.uuid_generate_v4() NOT NULL,
Right now I've got that set to NULL to allow the parser to "compile".
What value should I have in here since I want a newly created UUID?
CREATE RULE log_accessor AS ON UPDATE TO iss.accessor
WHERE NEW.* <> OLD.*
DO INSERT INTO iss.auditaccessor VALUES (NULL,
'C',
new.loaddtlid,
new.seqno,
new.billable,
new.payind,
new.code,
new.description,
new.ref,
new.tractororcarrierflag,
new.tractororcarrierno,
new.tractorpct,
new.charge,
new.type,
new.checkdate,
new.checkno,
new.processed,
new.itemflag,
new.tractortermloc,
new.cost,
new.batchno,
new.editdatetime,
new.edituser);

INSERT INTO table (serial_col1) VALUES (DEFAULT);
Also, I presume you have a good reason for using a RULE instead of a TRIGGER? If not you should default to a TRIGGER
forthis kind of behavior.
