Question

create or replace TRIGGER "VALIDATE_DOA_DOD" BEFORE UPDATE ON IN_PATIENT 
FOR EACH ROW
BEGIN
  IF :NEW.DOD < :OLD.DOA THEN


    enter code here


 RAISE EX_INVALID_DOD;
  END IF;

  EXCEPTIION
    WHEN EX_INVALID_DOD THEN
      dbms_output.put_line('Date Of Discharge must be greater or equal to Date of Admition');

END;

Answer 1

1. 用有意义的东西替换'enter code here'，或删除它
2. 编辑EXCEPTIION成EXCEPTION
3. 声明你的例外EX_INVALID_DOD

所以：

create or replace TRIGGER "VALIDATE_DOA_DOD" BEFORE UPDATE ON IN_PATIENT 
FOR EACH ROW
declare
    EX_INVALID_DOD exception;
BEGIN
  IF :NEW.DOD < :OLD.DOA THEN


     --enter code here


     RAISE EX_INVALID_DOD;
  END IF;

  EXCEPTION
    WHEN EX_INVALID_DOD THEN
      dbms_output.put_line('Date Of Discharge must be greater or equal to Date of Admition');

END;
