ORA-25029: compound triggers should always start with keyword COMPOUND

文档解释

ORA-25029: compound triggers should always start with keyword COMPOUND

Cause: Compound trigger body was started with incorrect keyword.

Action: Fix the syntax and recreate.

ORA-25029是一个错误信息,它指出Oracle不允许任何复合触发器(Trigger)创建而没有以关键字“COMPOUND”开头。

官方解释

ORA-25029被定义为错误,指出复合触发器(Compound Trigger)必须以“COMPOUND”关键字开头。ORA-25029表明您正在尝试创建一个少了“COMPOUND”关键字的复合触发器,因此必须重新编写SQL语句,并以Compound作为关键字开头。

常见案例

误写:

CREATE OR REPLACE TRIGGER trg

BEFORE INSERT ON sample

FOR EACH ROW

BEGIN

//Triggger Logic

END;

正确写法:

CREATE OR REPLACE TRIGGER trg

COMPOUND

BEFORE INSERT ON sample

FOR EACH ROW

BEGIN

// Triggger Logic

END;

一般处理方法及步骤

1. 阅读错误消息,理解被触发的异常是什么。

2. 查阅有关Oracle复合触发器(Compound Triggers)文档,确保你正在正确使用“COMPOUND”关键字。

3. 修改触发器,确保它以“COMPOUND”关键字开头。

4. 尝试重新编译触发器。

5. 如果编译失败,请调查隐藏的错误原因,并重新调整触发器的SQL语句。
