Hi,
please try this code:
CREATE OR REPLACE TRIGGER <tiggername>
AFTER INSERT OR UPDATE
ON TT
FOR EACH ROW
DECLARE
v_Status varchar2(10);
BEGIN
-- Insert record into audit table
INSERT INTO orders_audit
( id,
name,
stage)
VALUES
( :new.id,
:new.name,
:new.stage);
select stage into v_status
from tt where stage = new.stage
update tt set status = v_status where id = new.id
END;
