투한 2012. 2. 13. 09:22



DB연동 패턴 (Dao.java)
Date Access Object(DAO) 

1.목록 (ArrayList + 자바빈)
2.상세정보 (자바빈, ex select * from guestbook where num =?)
3.insert
4.update (1.인증 -> 2.update)
5.delete (1.인증 -> 2.delete) 


DB생성

create table guestbook(

num number primary key,

register date not null,

name varchar2(20) not null,

email varchar2(40),

passwd varchar2(10) not null,

content varchar2(4000) not null

);

create sequence guestbook_seq;
