join fetch 까지 했는데 잘 안됩니다

안녕하세요 선생님,

강의를 듣고 있는 중에 join fetch 가 안되서 여쭤봅니다

아래는 join fetch 가 실행되어야 할 부분인데 skip 하고 실행이 안되는 console  내용입니다.

update item set name='SPRING2 BOOK', price=40000, stock_quantity=296, author=NULL, isbn=NULL where item_id=10;

설명하셨던 코드들 다 작성 잘 했는데 왜 join fetch 가 실행이 안되는지 모르겠습니다 

아래 제가 작성했던 코드를 깃허브로 첨부해드립니다
