Set2 - 1번 문제 풀이를 보고 같게 작성 후 코드를 돌렸는데 답이 이상하게 나옵니다.SELECT city , length(city) lenFROM STATIONORDER BY len, cityLIMIT 1;SELECT city , length(city) lenFROM STATIONORDER BY len DESC, cityLIMIT 1이렇게 작성 후 돌리면 다음과 같이 나오네요왜 이럴까요...?submit code를 눌러도 오답이라고 뜹니다. 

선생님, 안녕하세요 현 강의 수강생입니다.강의해서 말씀해 주신 것처럼 아나콘다를 통해 주피터 노트북을 설치했는데 아래 첨부한 이미지처럼 계속 여러가 뜹니다.. 선생님께서 올려주신 유툽 영상도 따라해 보고 구글에 검색해 따라해 봐도 주피터 자체를 실행할 수 없는 에러가 뜹니다.. 어떻게 해야 할까요ㅠㅠㅠ 답 주시면 감사하겠습니다...   

안녕하세요 루키스님!리뉴얼 된 강의를 보다가 갑자기 사라졌는데, 혹시 새로 만드시는 중이신가요?만약 새로 만드시는 중이시라면 혹시 언제쯤 강의가 완성될지 알 수 있을까요?

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예/아니오)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오)[질문 내용]여기에 질문 내용을 남겨주세요.MemberRepositoryTest에 @SpringBootTest를 사용했는데, @DataJpaTest로는 안되는 건가요 ?

C++은 실전문제에 대한 강의가 없나요? 자바나 파이썬은 있는데 없는거 같아서요.

안녕하세요. 강의 열심히 보고 있습니다. ^^JobQueue #1 강의중 19분51초에서..멀티스레드 환경에서14줄에서 null 체크를 하고접속이 해제된다면17줄에 room을 넣을 때null이 반환되지 않을까요?? 검색해봐도 해당 내용은 없는거 같아서 질문 드립니다.

혹시 정보가 있으시다면 이번 회차(2023.3월~4월)의 지난 시험에는 어떤 유형이 나왔는지 궁금합니다.남은 하루동안 D, E 유형이 난이도 조정을 위해 새로 생긴 만큼 아주 집중적으로 공부하는편이 좋을지, 아니면 A~C 최종 복습을 하고 갈지 선택하려구요.. 물론 다 잘 해야겠지만요 ^^;;내일 시험이라 걱정이 많이 되고 떨리네요.

안녕하세요.드디어 완강을 하게 되었습니다! 여러번 복습을 해야겠지만 일단 너무 감격스럽네요 ㅜㅜ다름 아니라, 완강후 완성된 코드에서는 주문 탭에서 force refetch를 하면 주문 내용이 새로고침 되지가 않습니다.throttle과 debounce 를 적용하기 전에는 결제 내용이 주문 탭에 즉시 반영되지는 않아도, force refetch를 하면 반영되었거든요.깃헙에 올려주신 소스코드로도 같은 증상입니다.다른 탭에서의 force refetch는 이상없이 작동하는데 왜 그럴까요?

과제를 하면서 css 수정하면서 구글링 해봐도 해결이 안되는 부분이 있어 질문드립니다! export const SubmitBtn = styled.button` height: 52px; padding: 14px 60px; background-color: ${props => props.color}}; border: none; font-style: normal; font-weight: 500; font-size: 16px; line-height: 24px; margin-top: 74px; box-sizing: border-box; cursor: pointer; `수정하기/ 취소하기 버튼 CSS입니다. 이렇게 작성했을 때..이렇게 나옵니다. 분명 border: none; 을 작성해줬는데 적용이 안됩니다.이상해서 CSS 속성 하나씩 지워줬을 때,export const SubmitBtn = styled.button` height: 52px; padding: 14px 60px; // background-color: ${props => props.color}}; border: none; font-style: normal; font-weight: 500; font-size: 16px; line-height: 24px; margin-top: 74px; box-sizing: border-box; cursor: pointer; `이런식으로 background-color(또는background 속성)를 주석으로 처리하니 아래 사진처럼 테두리 선이 사라졌습니다.background 속성을 줬을 때 border: none 도 안먹히고 cursor: pointer; 속성도 안먹히던데 뭐가 문제인걸까요..ㅜㅜ

선생님 안녕하세요!마우스를 올렸을때 실행되는 함수로 mouseover를 알고있었는데, 선생님은 mouseenter를 사용하시더라구요!혹시 mouseenter랑 mouseover랑 차이점이 있을까요?? 

항상 Member객체를 만들고 시작하시는 것 같은데, 실제로는 멤버객체가 이미 있고 그걸 find하든 save하든 할거아니예요?? Test할땐 항상 처음부터 시작한다고 생각하고 로직을 짜나요??그리고 Test코드를 작성하는 이유는 무엇인가요? 기능 테스트를 할 때 항상 postman으로 했는데 그렇게 하는 것과 차이점이 있을까요 ???그리고 테스트코드에서는 main 디렉토리에 있는 클래스를 자유롭게 접근할 수 있는건가요? 예시에서도 MemoryMemberRepository를 쓰시길래 궁금해서 여쭤봅니다

안녕하세요. 스프링 환경에서 elasticbeanstalk과 github actions를 활용해 CI / CD를 연습하고 있는 학생입니다. 프로젝트를 만든 다음 CI / CD를 하는 과정에서 에러가 생겨 간단한 프로젝트 파일을 다시 만든 뒤 (루트 페이지에 텍스트 뜨는) CI / CD 작업을 하고 있는데, 아래처럼 502 헬스 체크 에러가 뜨고 있는 문제가 발생하고 있습니다. 혹시 해당 오류를 해결하신 분이 있다면 도움 부탁드립니다..!작성한 nginx.conf 파일은 아래와 같습니다. 일단 5000번 포트를 쓰는 것 같아 upstream, proxy_pass를 5000으로 작성하였습니다.

(factoryCode는 외래키가 아닙니다! 찾아보니 일대일 매핑만 나왔습니다ㅠㅠ)읽기전용이 아닌 prodPlan 테이블의 ITEM_CODE와 Item 테이블의 MATERIAL_CODE를 조인하려 했는데요. 그럴려면 @Column itemCode를 지우고 사용해야 중복컬럼에러를 피할 수 있었습니다. @Column itemCode를 선언하고 조인하는 방법은 없을까요?

[42104-214] org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [select * from member where name = ?]통합테스트를 진행시키면 위와 같은 에러가 나옵니다.강의를 들으면서 MemberServiceIntegrationTest.java를 작성했고, jdbc 템플릿을 이용해 db 구축도 했습니다. 오타가 있는지 계속 확인해보았지만 오타로 보이는것이 없어 질문 올립니다. 스프링이 완전 처음이라 강의를 100퍼센트 이해하면서 코드를 따라 짜지 못했기 때문에, 질문을 정확하고 자세하게 말씀 못드려서 죄송합니다...https://github.com/ffe4el/Spring_prj/tree/main/hello-spring오류가 나는 코드를 깃허브 위 주소에 올려놓았습니다. 살펴봐주세요...ㅠ 

webpack을 실행하면 dist폴더에 app.js가 저장되고 이것을 실행하면서 react가 실행되었는데 핫리로딩을 할때는 dist폴더가 필요없고app.js도 안만들어지는것 같습니다 설정에서는 dist와 app.js를 명시하고 있는데 핫리로딩을 어디에서 app.js를 저장하는 건가요? 

#include <iostream>using namespace std;// 다중 포인터void SetMessage(const char* a){ a = "Bye"; }void SetMessage(const char** a){ *a = "Bye";}int main(){ // .rdata [H][e][l][l][o][\0] char형 배열 형태 // main stackframe msg[ Hello주소 ] << 8바이트 const char* msg = "Hello"; // [매개변수][RET][지역변수(msg(Hello주소))] [매개변수(a(Bye주소))][RET][지역변수] SetMessage(msg); cout << msg << endl; // .rdata [H][e][l][l][o][\0] char형 배열 형태 // msg [ Hello주소 ] << 8바이트 // pp[ &msg ] << 8바이트 const char** pp = &msg; SetMessage(pp); cout << msg << endl; return 0;} 메모리를 찬찬히 까보면서 확인했는데궁금한점이 있어서 글 남깁니다  1.void SetMessage(const char** a){ *a = "Bye";} 이 부분이 실행되고 난 뒤에 msg의 시작주소가 Hello주소가 아닌 Bye 주소를 나타내고있는데원래 포인터를 이용하면 해당 주소로 텔레포트 후 그 주소의 데이터에 직접 접근해서 데이터를 변경하는 것으로 알고있습니다그런데 문자열은 .rdata로 수정불가하기 때문에 단순히 msg가 가리키는 주소만 변경해서즉, msg의 시작주소가 Hello주소가 아닌 Bye의 시작주소를 가리키게 된건가요? 2.함수 호출이 끝난 뒤에는 Bye주소에 해당하는 값인 문자열 "Bye"는 메모리상에 데이터로 남아있던데이 데이터가 사라지지 않는 이유를 잘 모르겠습니다.스택 프레임 구조에서 [매개변수][RET][지역변수] 이 세가지만 없어지게 되서 그런건가요?  

이전 문의내용인데 혹시 방법이 없을까요?ㅜㅜ한글 2022인데 그것과 상관있을까요? 그전버전에서는 이상없었습니다.#Python#한컴오피스

같은 질문 해주신 글을 보았는데,실제 컴퓨터의 ip를 넣어주어야 한다는 답변을 써주셨던데login_screen.dart 파일에서final emulatorIp = '';final simulatorip = '';이 부분의 ip주소만 바꾸면 되는게 맞나요?어느 부분을 더 수정해야 하는지 궁금합니다..  

안녕하세요 학습내용중에 ansible vault 를 젠킨스에서 사용하는 방법에 관한 추가 강의가 있었으면 좋을거 같아 문의드립니다감사합니다
