1) 전체 추가
INSERT INTO table_name VALUES(값, 값..)
=> 문자, 날짜 => ''
=> 데이터베이스 순서대로 입력
2) 원하는 데이터만 추가
INSERT INTO table_name(컬럼명, 컬럼명..) VALUES(값, 값..)
3) 다른 테이블에 있는 데이터 전체를 추가
INSERT INTO table_name SELECT * FROM table_name
4) 같은 데이터를 여러 테이블에 저장
INSERT ALL
= UPDATE (데이터 수정)
UPDATE table_name SET
컬럼명 = 변경할 값, 컬럼명 = 변경할 값...
===============================> 전체 데이터가 변경
[WHERE 조건]
= DELETE (데이터 삭제)
DELETE FROM table_name => 전체 데이터가 삭제
