错误ORA-04079：无效的触发器规格

Question

是否可以在一个触发器中有多个表？假设我有员工，技能和客户表，并且我有Eventlogs表来捕获审计。我试图添加Skill_T，但是我得到了ORA-04079错误。任何更正？谢谢！

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触发器关联（绑）只有一个表。它仅在针对该表提交DML时执行。 请参阅http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/triggers.htm#LNPLS99888
