Hi All Its been some time since I did any work using triggers/pgsql and when I did, it was pretty much basic stuff. Ive now returned to developing apps using postgres and have run into an error when using a trigger that I wrote a few years back (which worked fine then) but doesnt seem to work anymore! I must have changed something (?) but can't remb what! When I try to insert a record into a table called "stage" which should then fire my trigger i get the following error message: org.postgresql.util.PSQLException: ERROR: record "old" is not assigned yet Detail: The tuple structure of a not-yet-assigned record is indeterminate. Here is the code for the trigger:- CREATE OR REPLACE FUNCTION createstagesubjectlisting() RETURNS "trigger" AS $BODY$ Declare Begin IF (((TG_OP = 'INSERT') AND (new.subjects=TRUE)) OR ((TG_OP='UPDATE') AND (new.subjects=TRUE) AND (old.subjects=FALSE))) THEN Insert into subsperstage(stageid, subno) VALUES (new.stageid, 10); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 20); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 30); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 40); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 50); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 100); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 200); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 300); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 400); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 500); Insert into subsperstage(stageid, subno) VALUES (new.stageid, 1000); END IF; IF ((TG_OP='UPDATE') AND (new.subjects=FALSE) AND (old.subjects=true)) THEN DELETE FROM subsperstage where stageid=old.stageid; end if; Return NULL; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE; ALTER FUNCTION createstagesubjectlisting() OWNER TO postgres; the trigger on table: CREATE TRIGGER createstagesubjectlisting AFTER INSERT OR UPDATE ON stage FOR EACH ROW EXECUTE PROCEDURE createstagesubjectlisting(); Removing the trigger everything works fine - records get inserted into my stage table, but having the trigger results in no data being inserted in my stage table or the trigger being fired. Any ideas???
