[Spring] 다중 삽입하기 - 객체 (+ checkbox, select)

아잠만_ 2024. 8. 2. 14:46

INSERT ALL

동일한 하나의 서브 쿼리 결과 값을

두 개 이상의 테이블에 각각 INSERT 할 때 사용

해당 문은 다중 삽입시 사용함

INSERT ALL
INTO 테이블명1 VALUES (컬럼명, 컬럼명 ,컬럼명)
INTO 테이블명2 VALUES (컬럼명, 컬럼명 ,컬럼명)
서브쿼리;

해당 작업에는 이와같이 carsVoList에 담아 foreach문을 통해 데이터를 여러 개 삽입하였는데

이때 insert문임에도 불구하고 update로 작성하는 것이 약속이다

	<update id="insertCars"  parameterType="java.util.List">
	    <foreach collection="list" item="item" open="INSERT ALL" close="SELECT * FROM DUAL" separator=" " index="idx">
	        INTO cars(user_id, car) VALUES (#{item.userId}, #{item.car})
	    </foreach>
	</update>

SQL

VO객체에 한 List<Vo객체>가 포함될 경우 list에 있는 정보들 또한 삽입하는 방법을 기술한다.

이를 연습하기위해 테이블 두개를 추가하도록 한다

create table tbl_user(
    user_id varchar2(10),
    password varchar2(100),
    name varchar2(90),
    email varchar2(100),
    bir varchar2(50),
    zipCode varchar2(10),
    addr varchar2(300),
    addrdet varchar2(1000),
     constraint pk_user primary key(user_id)
)

create table card(
    card_no number,
    cart_ym varchar2(10),
    user_id varchar2(10) not null,
    constraint pk_card primary key(card_no),
    constraint fk_card foreign key(user_id)
        References TBL_USER(USER_ID)
)

create table tbl_hobby(
    user_id varchar2(10) not null,
    hobby varchar2(20),
     constraint pk_hobby_user primary key(user_id, hobby),
     constraint fk_hobby_user foreign key(user_id)
        References TBL_USER(USER_ID)
)

create table cars(
    user_id varchar2(10) not null,
    car varchar2(50),
     constraint pk_car_user primary key(user_id, car),
     constraint fk_car_user foreign key(user_id)
        References TBL_USER(USER_ID)
)

해당 List에 있는 cardVO List들은 반복문 for을 통해서 하나씩 insert작업을 수행한다

이러한 과정은 ServiceImpl에서 이루어진다
