ORACLE触发器简单列子

场景：

触发器 ,数据插入表1后，同时把数据插入表2

（sql语句在plsql亲测过，可行。这里每次插入表1 都会把表1的数据全部在插入表2，数据会重复）

--表1
create table student
(
  id       VARCHAR2(32) not null,
  name     VARCHAR2(8) not null,
  age      NUMBER(13,3),
  birthday DATE,
  address  VARCHAR2(200)
)

--表2
create table student_two
(
  id       VARCHAR2(32) not null,
  name     VARCHAR2(8) not null,
  age      NUMBER(13,3),
  birthday DATE,
  address  VARCHAR2(200)
)
--触发器 ,插入表1后，同时把数据插入表2
CREATE OR REPLACE TRIGGER stu_tri
AFTER INSERT
ON student
BEGIN
INSERT INTO student_two (ID, NAME, AGE, BIRTHDAY, ADDRESS)
SELECT ID, NAME, AGE, BIRTHDAY, ADDRESS FROM STUDENT ;
END stu_tri ;


delete from student;
delete from student_two;
commit;

insert into STUDENT (ID, NAME, AGE, BIRTHDAY, ADDRESS) values ('1', '张三', 11.000, to_date('01-08-2010', 'dd-mm-yyyy'), '广州');
insert into STUDENT (ID, NAME, AGE, BIRTHDAY, ADDRESS) values ('2', '李四', 9.000, to_date('11-06-2012', 'dd-mm-yyyy'), '深圳');
insert into STUDENT (ID, NAME, AGE, BIRTHDAY, ADDRESS) values ('3', '王五', 7.000, to_date('05-07-2014', 'dd-mm-yyyy'), '上海');
commit;

select * from student order by id;
select * from student_two order by id;
