테이블 만들기

create table file_board(
bno number primary key,
title varchar2(100) not null,
content VARCHAR2(1000) not null,
writer VARCHAR2(50) not null);

create SEQUENCE seq_file_board;

CREATE TABLE save_file(
fno number PRIMARY KEY,
file_name VARCHAR2(200) not null,
bno number REFERENCES file_board(bno));

CREATE SEQUENCE seq_save_file;


Save_file 제약조건 > 왜래키 > 삭제 시 설정 조정한다.
널 설정, 종속삭제 두 가지가 있는데 종속삭제는 bno를 지웠을 때 같이 지워진다.
