이 두가지 에러는 각각 다르지만 해결책은 똑같기에 한번에 정리해서 쓴다.

 

 

1. 시퀄라이즈 sequelize에서 테이블을 생성 및 수정했는데 MySQL DB 데이터베이스에 반영이 안 될때.

2. 테이블 내 컬럼명을 바꾸고 서버를 켜서 썬더클라이언트를 했더니 400 Bad Request 나올 때.

 

테이블이 없는데도 업데이트 이미 되있다고 마이그레이션이 안될 때가 있다.

 

sequelize는 SequelizeMeta라는 테이블을 만들어서 migration 상태를 저장한다.

undo할 때 여기 저장된 migration 정보를 읽어서 down을 실행시키는 것 같다.

select * from "SequelizeMeta";

하고 있으면

drop table "SequelizeMeta";

 

SequelizeMeta 테이블에 들어가서, 순서대로

 

DELETE FROM SequelizeMeta;
SELECT * FROM SequelizeMeta; // 비워짐
npx sequelize db:migrate // 터미널에 씀

SELECT * FROM SequelizeMeta; // 생성됨

 

이렇게 하면 된다.

SequelizeMeta에는 migration 정보를 갖고있어서 이런식으로 해결이 가능하다. 아래는 에러 전문.
