H2 Database 사용 에러 질문드립니다.

안녕하세요. 강의 정말 잘 듣고 있습니다. MVC나 부트 JPA 모두 정말 좋은 강의 감사드려요

커뮤니티에 글을 올리게 된 이유는.. 일단 부트 JPA 실전 1편 강의를 다 들었고 그동안

H2 Database를 잘 사용하였는데요, 그 다음 과정으로는 JPA 기본편을 들었고

이 때에는 뭐가 문제인지 H2 Database가 작동은 하는데, 실전 1편에서 생성한 테이블들이

삭제도 안되고 뭔가 락이 걸려있는것처럼 그래서 기본편 듣는동안은 테이블명을 일부러

기존에 Member가 있으니 Member1 이런식으로 만들어서 진행했었구요

그다음에 이제 다시 실전1편에서 사용한 프로젝트로 돌아와서, 처음부터 다 지우고

관계설정같은거 다 스스로 코드 짜서 이제 Test코드 딱 돌렸는데. 테스트는 성공하는데

DB에 반영이 아예 안되더라구요

심지어 그 프로젝트는 H2 Database를 꺼놔도 OK가 되고, yml에 있는거 다 지워버려도

Test가 성공되는데 희한한건 Member join을 한 만큼 findAll()로 조회는 또 되더라구요

이게 도대체 무슨 상황인지 살짝 멘붕이 왔지만 그냥 안되겠다 셈 치고

다시 실전 1편 첫 설정대로 프로젝트를 새로 생성하고 H2 Database도 다시 깔았습니다.

근데 이번에는 아래처럼 오류가 엄청 나고 있어요

gradle은 강의자료에 있는거 그대로 복사했고, yml파일도 띄어쓰기도 꼼꼼히 확인했습니다.

지금 약 4시간정도 삽질했는데. 기존 프로젝트 다 날리고 다시 시작해도 좋으니

해결방법을 알고싶습니다. ㅜㅜ H2 Database가 싫어질 지경이에요

부탁드립니다!!
