Hi,
Thank you ALL for the fast help
it works fine with following code:
CREATE OR REPLACE FUNCTION synchronize () RETURNS trigger AS 'BEGIN
NEW.objectid := NEW.gid; RETURN NEW; END;' LANGUAGE plpgsql;
CREATE TRIGGER syncl_holz_lager AFTER INSERT ON holz_lagerplatz FOR EACH ROW
EXECUTE PROCEDURE synchronize();
Best Regards
Eugen

Betreff: Re: [SQL] Trigger
It requires a bit more work in PostgreSQL to create a trigger.
From the documentation: "It is not currently possible to write a
SQL-language trigger function. Trigger functions can be written in C or
in some of the available procedural languages."
I guess you will prefer to write the trigger in PL/pgSQL, have a look at
http://www.postgresql.org/docs/8.0/interactive/plpgsql-trigger.html
