錯誤ORA-04079：無效的觸發器規格

Question

是否可以在一個觸發器中有多個表？假設我有員工，技能和客戶表，並且我有Eventlogs表來捕獲審計。我試圖添加Skill_T，但是我得到了ORA-04079錯誤。任何更正？謝謝！

注：我使用的Oracle SQL Developer Oracle11gEE

CREATE OR REPLACE TRIGGER AUDIT_REC 
AFTER INSERT OR DELETE OR UPDATE ON EMPLOYEE_T, SKILL_T 
FOR EACH ROW 
DECLARE 
    V_LOGID NUMBER; 
    V_USER VARCHAR(30); 
    V_DATE VARCHAR(30); 

BEGIN 
    SELECT EVENTLOG_ID_SEQ.NEXTVAL, USER, SYSDATE INTO V_LOGID, V_USER, V_DATE FROM DUAL; 
    IF INSERTING THEN 
    INSERT INTO EVENTLOGS(Eventlog_id, User_name, Date_done, Action_done) 
    VALUES (V_LOGID, V_USER, V_DATE, 'INSERT'); 
    ELSIF DELETING THEN 
    INSERT INTO EVENTLOGS(Eventlog_id, User_name, Date_done, Action_done) 
    VALUES (V_LOGID, V_USER, V_DATE, 'DELETE'); 
    ELSIF UPDATING THEN 
    INSERT INTO EVENTLOGS(Eventlog_id, User_name, Date_done, Action_done) 
    VALUES (V_LOGID, V_USER, V_DATE, 'UPDATE'); 
    END IF; 
END;

DML觸發器關聯（綁）只有一個表。它僅在針對該表提交DML時執行。 請參閱http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/triggers.htm#LNPLS99888
