oracle表创建序列创建触发器创建

// 创建一个序列
CREATE SEQUENCE Car_GUID increment by 1;
// 创建一个表
CREATE TABLE Car
(
GUID NUMBER NOT NULL PRIMARY KEY,
PhoneId Char(11) NOT NULL,
UserName VarChar(20) NOT NULL
);
// 添加注释
comment on table car is '定位信息用户表';
Comment on column car.guid is '自增字段';
Comment on column Car.PhoneId is '电话唯一标识';
Comment on column Car.UserName is '用户名称';
// 添加一条记录
INSERT INTO Car(GUID, PhoneId, UserName) Values(CAR_GUID.nextval, '13589256783', '张三');
// 提交
commit;

// 触发器
create or replace trigger Trigger_Car_GUID_Insert 
before insert on Car
for each row
begin
select CARGUIDSEQ.nextval into  :new.GUID from sys.dual;
end;

---给两表增加序列
--CREATE SEQUENCE STUBASEINFO_ID increment by 1;
--CREATE SEQUENCE STURESUME_ID increment by 1;


---给两表新增一条数据信息（测试）
