I think you have created a statement level trigger (If they existed in
7.4.7...) by not including FOR EACH ROW in your create statement. In
statement level triggers, there is no OLD or NEW.

Hello all,
I am trying to a simple thing: create a log history of deletes, and
updates; but which I am having trouble getting to work in PG 7.4.7
(under Debian Linux 2.6.8).
I have reduced my code to the following trivial case:
Here is the code that creates the delete trigger:
create trigger PEDIGREES_hist_del_trig
AFTER DELETE
on PEDIGREES
EXECUTE PROCEDURE logPedigreesDel();
Here is the trigger code: (famindid is an integer field in the Pedigrees
table):
CREATE OR REPLACE FUNCTION logPedigreesDel() RETURNS TRIGGER AS '
DECLARE
test integer;
begin
test := OLD.famindid;
RAISE EXCEPTION ''OLD.famindid = '', test;
return OLD;
end;
' LANGUAGE plpgsql;
Here is the error message returned:
psql:testphdtrig.sql:1: ERROR: record "old" is not assigned yet
DETAIL: The tuple structure of a not-yet-assigned record is
indeterminate.
CONTEXT: PL/pgSQL function "logpedigreesdel" line 4 at assignment
Would *really appreciate* any suggestions! This could help us decide
whether to PostGres for a major project...
thanks --rick
