データベースを MS SQL から MySQL に移行しました。

レポートを実行すると、次のエラーが表示されるようになりました。

Application Execution Exception

            responseYear ASC

どうすれば解決できますか？

ありがとう

ある場所で two 句を使用しています。DISTINCT と TOP を使用しているため、エラーが発生します。

次のクエリを使用します。

SELECT DISTINCT YEAR(res_created) AS responseYear 
       FROM Responses 
           INNER JOIN Questions ON Responses.question_id = Questions.question_id 
           INNER JOIN Lookup_Survey_Questions ON Questions.question_id = Lookup_Survey_Questions.question_id 
           INNER JOIN Survey ON Lookup_Survey_Questions.survey_id = Survey.survey_id 
           INNER JOIN School ON Survey.sch_id = School.sch_id INNER JOIN Authority ON School.auth_id = Authority.auth_id 
           WHERE Authority.auth_id = 5 AND Questions.question_id = 20 AND Responses.survey_id IN (
            SELECT Survey.survey_id FROM Survey where Survey.sch_id in (SELECT School.sch_id FROM School where auth_id=5)) 
           ORDER BY responseYear ASC
           LIMIT 0,2; //use the limit

これは次のように単純化できると思います...

SELECT DISTINCT YEAR(res_created) responseYear
  FROM Responses r
  JOIN Questions q
    ON q.question_id = r.question_id 
  JOIN Lookup_Survey_Questions lsq
    ON lsq.question_id = q.question_id 
  JOIN Survey u
    ON u.survey_id = lsq.survey_id
  JOIN School c
    ON c.sch_id = u.sch_id
  JOIN Authority a
    ON a.auth_id = c.auth_id
 WHERE a.auth_id = #arguments.authorityID#
   AND q.question_id = #arguments.questionID#
   AND c.auth_id=#arguments.authorityID#
 ORDER 
    BY responseYear ASC
 LIMIT 2;
