4일차 ibitis로 게시판 구현

1.게시판에 사용될 테이블 만들기

sql

CREATE TABLE board(
	seq int auto_increment primary key, //글번호
	writer varchar(20) not null,     // 글쓴이
	title varchar(100) not null,     // 글제목
	content mediumtext,            //글내용
	pwd varchar(20) not null,      // 글 비밀번호
	hit decimal(5,0) not null,        // 조회수
	groups decimal(10,0) not null, //글 그룹(답글 용)
	step decimal(3,0) not null,     //답글의 순서
	level decimal(3,0) not null,    //첫번째 답글이냐 두번째 답글이냐
	bname varchar(10) not null,   // 게시판 이름** bname="식물"  bname="물고기"
	regdate datetime not null     //글 등록시간
	);
