Oracle 怎么让id自增加

--自增长序列
create table test(
  tid int not null,
  tname varchar(20),
  tsex varchar(20),
  tbz varchar(50)
)
--添加主键约束
alter table test add constraint test_pk primary key (tid)
--自增序列
create sequence test_seq
minvalue 1
maxvalue 1000
start with 1
increment by 1
--插入数据
insert into test values(test_seq.nextval,'张三','男','无备注');
insert into test values(test_seq.nextval,'李四','男','组长');
