mysql row를 어떻게 만들지?
테이블 작성을 어떻게 했더라??
DESC 테이블이름;
DESC topic;
** READ == SELECT
SELECT * FROM 테이블이름;
SELECT * FROM topic;
# 전부 보고 싶으면? => * 로 모든 컬럼 선택
일부만 보고 싶으면?
SELECT 보고싶은 컬럼이름 FROM 테이블이름;
SELECT id,title,description FROM topic;
원하는 것만 선택해서 보자. WHERE문
SELECT 보고싶은 컬럼이름 FROM 테이블이름 WHERE 컬럼='값';
SELECT id,title,description FROM topic WHERE author='Jaeuk-YOO';
근데 양이 오지게 많으면 문제가 좀 생기겠죠?
