mysql 쿼리 구문 오류

Question

아래의 쿼리에서 maxscore = score라는 퀴즈 만 가져오고 싶습니다. 구문에 무엇이 잘못 되었습니까?

$database->setQuery('SELECT distinct qui.title AS name,' . 
     ' (SELECT GROUP_CONCAT(profiles.title) 
       FROM #__jquarks_users_profiles AS users_profiles 
       LEFT JOIN #__jquarks_profiles AS profiles ON users_profiles.profile_id = profiles.id 
       WHERE users_profiles.user_id = sessionWho.user_id) AS profile, ' . 
     ' (SELECT sum(score) 
       FROM #__jquarks_quizzes_answersessions 
       WHERE quizsession_id = quizSession.id 
       AND status <> -1) AS score,' . 
     ' (SELECT count(distinct(question_id)) 
       FROM #__jquarks_quizzes_answersessions 
       WHERE quizsession_id = quizSession.id) AS maxScore,' . 

      ' (SELECT count(id) 
       FROM #__jquarks_quizzes_answersessions 
       WHERE status=-1 
       AND quizsession_id = quizSession.id) AS evaluate,' . 
' quizSession.finished_on,sessionWho.email' .  
     ' FROM #__jquarks_quizsession AS quizSession' . 
     ' LEFT JOIN #__jquarks_users_quizzes AS users_quizzes ON users_quizzes.id = quizSession.affected_id' . 
     ' LEFT JOIN #__jquarks_quizzes AS qui ON users_quizzes.quiz_id = qui.id' . 
     ' LEFT JOIN #__jquarks_quizzes_answersessions AS quizSessAns ON quizSessAns.quizsession_id = quizSession.id' . 
     ' LEFT JOIN #__jquarks_sessionwho AS sessionWho ON sessionWho.session_id = quizSession.id' . 
     ' LEFT JOIN #__jquarks_users_profiles AS users_profiles ON users_profiles.user_id = sessionWho.user_id' . 
' LEFT JOIN #__jquarks_profiles AS profiles ON profiles.id = users_profiles.profile_id '. 

' WHERE sessionWho.user_id =' .$id AND score = maxScore) ;

Answer 2

마지막 부분, AND score = maxScore 따옴표에 넣어되지 않습니다. 이것은 또한 SQL 문자열의 일부 여야합니다.

질문의 코드에 적용된 강조 표시에서도 쉽게 확인할 수 있지만 편집기의 형광펜도이를 분명히해야합니다. NetBeans 또는 Notepad ++와 같은 편집기를 사용합니까?

$database->setQuery('SELECT distinct qui.title AS name,' . 
     ' (SELECT GROUP_CONCAT(profiles.title) 
       FROM #__jquarks_users_profiles AS users_profiles 
       LEFT JOIN #__jquarks_profiles AS profiles ON users_profiles.profile_id = profiles.id 
       WHERE users_profiles.user_id = sessionWho.user_id) AS profile, ' . 
     ' (SELECT sum(score) 
       FROM #__jquarks_quizzes_answersessions 
       WHERE quizsession_id = quizSession.id 
       AND status <> -1) AS score,' . 
     ' (SELECT count(distinct(question_id)) 
       FROM #__jquarks_quizzes_answersessions 
       WHERE quizsession_id = quizSession.id) AS maxScore,' . 

      ' (SELECT count(id) 
       FROM #__jquarks_quizzes_answersessions 
       WHERE status=-1 
       AND quizsession_id = quizSession.id) AS evaluate,' . 
' quizSession.finished_on,sessionWho.email' .  
     ' FROM #__jquarks_quizsession AS quizSession' . 
     ' LEFT JOIN #__jquarks_users_quizzes AS users_quizzes ON users_quizzes.id = quizSession.affected_id' .

' WHERE sessionWho.user_id =' .$id . ' AND score = maxScore') ; 

추 신 : 실제로 테이블 이름에 #이 포함되어 있습니까?

LEFT JOIN `#__jquarks_users_profiles`
