감사합니다!

안녕하세요. 조동희님^^

다음 예제를 참고해주세요.

List<Tuple> result = queryFactory
        .select(member.username,
                Expressions.as(select(memberSub.age.avg())
                        .from(memberSub), "subAgeAvg")
        )
        .from(member)
        .fetch();

for (Tuple tuple : result) {
    System.out.println("tuple.username="+tuple.get(member.username));
    System.out.println("tuple.subAgeAvg="+tuple.get(Expressions.numberPath(Double.class, "subAgeAvg")));
    System.out.println("tuple.get(1, Double.class) = " + tuple.get(1, Double.class));
}
