oracle數據庫創建表,序列及添加代碼案例

create table cdpt(

id number(6),

name varchar2(30),

constraint pk_id primary key(id)

);

 

更改數據庫的“延遲段創建”特性為false  在sql plus 中執行此句

ALTER SYSTEM SET deferred_segment_creation=FALSE;

創建序列

create sequence seq_cdpt

increment by 1

start with 1

maxvalue 99999

minvalue 1

NOCYCLE

nocache

注意,用ADO添加時,需加上commit,否則在vs中數據不顯示

insert into cdpt values(seq_cdpt.nextval,'feffefe');
commit;
