Member findMember = jpaQueryFactory
        .selectFrom(QMember.member)
        .join(member.team, team).fetchJoin()//뒤에 fetchJoin만 붙여주면 된다.
        .where(QMember.member.username.eq("member1"))
        .fetchOne();

jpaQueryFactory
        .select(QMember.member, team)
        .from(member)
        .join(member.team, team)
        .where(QMember.member.username.eq("member1"))
        .fetchOne();

첫번째건 fetchjoin을 사용한 것이고
두번째건 select(member, team) 하고 join 한 것인데

jqpl은 다르게 나가더라도 결국 sql 은 같게 나옵니다.

차이가 없는건가요?
