在Oracle怎样用将主键ID设置为自动增加

序列

create sequence FIXED_ASSETS_TYPE_SE
minvalue 1
maxvalue 9999999999999999999999999999
start with 1
increment by 1
nocache;

触发器

create or replace trigger FIXED_ASSETS_TYPE_TRI
before insert on FIXED_ASSETS_TYPE for each row
begin
select FIXED_ASSETS_TYPE_SE.nextval into :new.TYPE_ID from dual;
end FIXED_ASSETS_TYPE_TRI;

增加记录

INSERT INTO FIXED_ASSETS_TYPE(PARENT_ID,TYPE_NAME,DEL_FLAG) Values(1,'沙发',0);

//查询

select * from fixed_assets_type;
