Как мы можем указать, что триггер TRG_2 должен быть выполнен до триггера TRG_1 путем воссоздания триггера TRG_1 с использованием предложения execute?

Question

Я создал два триггера, имя триггера 1 TRIGGER_FOLLOWS_TEST_TRG_2 и имя триггера 2 TRIGGER_FOLLOWS_TEST_TRG_1.

Я хочу, чтобы триггер TRIGGER_FOLLOWS_TEST_TRG_2 выполнялся до триггера TRIGGER_FOLLOWS_TEST_TRG_1 путем воссоздания триггера TRIGGER_FOLLOWS_TEST_TRG_1.

create or replace TRIGGER TRIGGER_FOLLOWS_TEST_TRG_1
AFTER INSERT OR UPDATE
OF ISSA_STATUS_P, PRB_BEW_CODE
ON PROBE
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
EXECUTE TRIGGER_FOLLOWS_TEST_TRG_2
DECLARE
    V_STATUS VARCHAR2(10);
    V_BEW_CODE VARCHAR2(5);
BEGIN
    IF INSERTING OR UPDATING THEN
        V_STATUS := :NEW.ISSA_STATUS_P;
        V_BEW_CODE := :NEW.PRB_BEW_CODE;
    ELSE
        V_STATUS := :OLD.ISSA_STATUS_P;
        V_BEW_CODE := :OLD.PRB_BEW_CODE;
    END IF;

    IF (V_STATUS = 'PAF' AND V_BEW_CODE IS NULL) THEN
        RAISE_APPLICATION_ERROR (-20011, 'Error: Status is finalized but assessment code is null');
    END IF;

END TRIGGER_FOLLOWS_TEST_TRG_1;

и

create or replace TRIGGER TRIGGER_FOLLOWS_TEST_TRG_1
AFTER INSERT OR UPDATE
OF ISSA_STATUS_P, PRB_BEW_CODE
ON PROBE
DEFERRABLE INITIALLY DEFERRED
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
EXECUTE TRIGGER_FOLLOWS_TEST_TRG_2
DECLARE
    V_STATUS VARCHAR2(10);
    V_BEW_CODE VARCHAR2(5);
BEGIN
    IF INSERTING OR UPDATING THEN
        V_STATUS := :NEW.ISSA_STATUS_P;
        V_BEW_CODE := :NEW.PRB_BEW_CODE;
    ELSE
        V_STATUS := :OLD.ISSA_STATUS_P;
        V_BEW_CODE := :OLD.PRB_BEW_CODE;
    END IF;

    IF (V_STATUS = 'PAF' AND V_BEW_CODE IS NULL) THEN
        RAISE_APPLICATION_ERROR (-20011, 'Error: Status is finalized but assessment code is null');
    END IF;

END TRIGGER_FOLLOWS_TEST_TRG_1;

Я пробовал это:

create or replace TRIGGER TRIGGER_FOLLOWS_TEST_TRG_1
AFTER INSERT OR UPDATE
OF ISSA_STATUS_P, PRB_BEW_CODE
ON PROBE
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
EXECUTE TRIGGER_FOLLOWS_TEST_TRG_2
DECLARE
    V_STATUS VARCHAR2(10);
    V_BEW_CODE VARCHAR2(5);
BEGIN
    IF INSERTING OR UPDATING THEN
        V_STATUS := :NEW.ISSA_STATUS_P;
        V_BEW_CODE := :NEW.PRB_BEW_CODE;
    ELSE
        V_STATUS := :OLD.ISSA_STATUS_P;
        V_BEW_CODE := :OLD.PRB_BEW_CODE;
    END IF;

    IF (V_STATUS = 'PAF' AND V_BEW_CODE IS NULL) THEN
        RAISE_APPLICATION_ERROR (-20011, 'Error: Status is finalized but assessment code is null');
    END IF;

END TRIGGER_FOLLOWS_TEST_TRG_1;

Когда я создаю этот триггер, он показывает ошибку рядом с «ВЫПОЛНИТЬ».
