select * from formerProperty;

Answer 1

you forget to use delimiter:

CREATE OR REPLACE TRIGGER trg_after_delete_bill
AFTER delete
ON Property FOR EACH ROW
  
BEGIN

  INSERT INTO formerProperty VALUES(:OLD.Pid,
           :OLD.Branchid,:OLD.Ptype,:OLD.Paddress,:OLD.Pcity,
           :OLD.CurrentPrice,:OLD.Pstatus,:OLD.Pminprice, :OLD.Pmaxprice,:OLD.Agentid,:OLD.Appointmentid);
  
END;
/
DELETE FROM Property WHERE Pid= 1;

select * from formerProperty
