在pl/sql中创建触发器时获取编译错误

下面的代码由我的sql项目组成。我很难反复找到触发器编译错误

 Warning: Trigger created with compilation errors.

我正在使用oracle SQL。如果这些代码段不够，那么您可以在以下链接中找到整个项目：

试试这个：

CREATE OR REPLACE TRIGGER user1audit
BEFORE INSERT OR DELETE OR UPDATE ON user1
FOR EACH ROW  

BEGIN 

  IF INSERTING THEN
  INSERT INTO myaudit (new_name,old_name, user_name, entry_date, operation) VALUES(:NEW.NAME, Null , user, TO_CHAR(sysdate, 'DD/MON/YYYY HH24:MI:SS'), 'Insert');
  ELSIF DELETING THEN
  INSERT INTO myaudit (new_name,old_name, user_name, entry_date, operation) VALUES(NULL,:OLD.NAME, user, TO_CHAR(sysdate, 'DD/MON/YYYY HH24:MI:SS') , 'Delete');
  ELSIF UPDATING THEN
  INSERT INTO myaudit (new_name,old_name, user_name, entry_date, operation) VALUES(:NEW.NAME, :OLD.NAME, user, TO_CHAR(sysdate, 'DD/MON/YYYY HH24:MI:SS'),'Update');
  END IF;
END;
 /

你能显示完整的错误信息吗？@TimBiegeleisen先生，我只收到以下错误信息：警告：触发器是用编译错误创建的。欢迎光临。尽量使事情简单化，避免混淆。：-）是的，先生。我会尽力的。

CREATE OR REPLACE TRIGGER user1audit
BEFORE INSERT OR DELETE OR UPDATE ON user1
FOR EACH ROW  

BEGIN 

  IF INSERTING THEN
  INSERT INTO myaudit (new_name,old_name, user_name, entry_date, operation) VALUES(:NEW.NAME, Null , user, TO_CHAR(sysdate, 'DD/MON/YYYY HH24:MI:SS'), 'Insert');
  ELSIF DELETING THEN
  INSERT INTO myaudit (new_name,old_name, user_name, entry_date, operation) VALUES(NULL,:OLD.NAME, user, TO_CHAR(sysdate, 'DD/MON/YYYY HH24:MI:SS') , 'Delete');
  ELSIF UPDATING THEN
  INSERT INTO myaudit (new_name,old_name, user_name, entry_date, operation) VALUES(:NEW.NAME, :OLD.NAME, user, TO_CHAR(sysdate, 'DD/MON/YYYY HH24:MI:SS'),'Update');
  END IF;
END;
