下面是之后語句級觸發器的示例。每當對emp表執行插入、更新或刪除操作時，都會向empauditlog表添加一行來記錄日期、用戶和操作。

CREATE TABLE empauditlog (
    audit_date      DATE,
    audit_user      VARCHAR2(20),
    audit_desc      VARCHAR2(20)
);
CREATE OR REPLACE TRIGGER emp_audit_trig
    AFTER INSERT OR UPDATE OR DELETE ON emp
DECLARE
    v_action        VARCHAR2(20);
BEGIN
    IF INSERTING THEN
        v_action := 'Added employee(s)';
    ELSIF UPDATING THEN
        v_action := 'Updated employee(s)';
    ELSIF DELETING THEN
        v_action := 'Deleted employee(s)';
    END IF;
    INSERT INTO empauditlog VALUES (SYSDATE, USER,
        v_action);
END;

在以下命令序列中，使用兩個INSERT命令將兩行插入emp表中。這兩行的sal和comm列將使用一個UPDATE命令更新。最后，這兩行將使用一個DELETE命令同時被刪除。

INSERT INTO emp VALUES (9001,'SMITH','ANALYST',7782,SYSDATE,NULL,NULL,10);

INSERT INTO emp VALUES (9002,'JONES','CLERK',7782,SYSDATE,NULL,NULL,10);

UPDATE emp SET sal = 4000.00, comm = 1200.00 WHERE empno IN (9001, 9002);

DELETE FROM emp WHERE empno IN (9001, 9002);

SELECT TO_CHAR(AUDIT_DATE,'DD-MON-YY HH24:MI:SS') AS "AUDIT DATE",
    audit_user, audit_desc FROM empauditlog ORDER BY 1 ASC;

AUDIT DATE         AUDIT_USER           AUDIT_DESC
------------------ -------------------- --------------------
31-MAR-05 14:59:48 SYSTEM               Added employee(s)
31-MAR-05 15:00:07 SYSTEM               Added employee(s)
31-MAR-05 15:00:19 SYSTEM               Updated employee(s)
31-MAR-05 15:00:34 SYSTEM               Deleted employee(s)

empauditlog表的內容顯示觸發了多少次觸發器：其中為兩次插入分別觸發一次，為更新觸發一次（即使更改了兩行）以及為刪除觸發一次（即使刪除了兩行）。
