Re: [GENERAL] basic trigger using OLD not working?

Thanks much! That met with  partial success; but getting closer.

The error message about OLD went away (thankfully!), but there is still no data from the OLD variable. Here is the code again:

create trigger PEDIGREES_hist_del_trig
AFTER DELETE
on PEDIGREES
FOR EACH ROW
EXECUTE PROCEDURE logPedigreesDel();


CREATE OR REPLACE FUNCTION logPedigreesDel() RETURNS TRIGGER AS '
begin
    RAISE EXCEPTION ''OLD.famindid = '', OLD.famindid;
    return OLD;
end;
' LANGUAGE plpgsql;

Which when it fires results in:
cgb_lab_data=# \i testphdtrig.sql
psql:testphdtrig.sql:1: ERROR:  OLD.famindid =

Regards,
rick

I think you forgot FOR EACH ROW.  By default, the above creates a
STATEMENT trigger, in which you don't have access to individual rows.
