Hi,

Change it to a "BEFORE UPDATE" trigger, and set NEW.updated_date := now();

Otherwise each update produces another update produces another update....

Can anybody help me creating a trigger on update trigger with update statement as below. This trigger fires after update on a table called note to update the updated_date field.
 But when the table is updated the trigger is firing recursively.
 Anybody know what is the syntax I have to use in update statement.
 CREATE TRIGGER "trg_update_note_updated_date" AFTER UPDATE
ON "property"."note" FOR EACH ROW
EXECUTE PROCEDURE "property"."update_note_updated_date_trg"();
CREATE OR REPLACE FUNCTION "property"."update_note_updated_date_trg" () RETURNS trigger AS
$body$
begin
  /* New function body */
       UPDATE property.note SET updated_date=CURRENT_DATE
       WHERE note_id = NEW. note_id;
    return null;
end;
$body$
LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;
