hqlを使用する代わりにネイティブSQLクエリを作成し、問題に直面しました
宣言された序数パラメーターの数を超える位置。序数パラメータは 1 から始まることに注意してください。ポジション: 1
<sql-query name="GET_ARRAY_MAX_POINT_QUESTION">
<![CDATA[
select TEST.TEST_ID as testId, TEST.VERSION_ID as versionId,
PASSED_TEST.RESULT as userResult,
PASSED_TEST.TIME_COMPLITED as timeComplited,
sum(COMPLEXITY) as maxTestResult from QUESTION
JOIN TEST_QUESTION ON QUESTION.QUESTION_ID = TEST_QUESTION.QUESTION_ID
JOIN TEST ON TEST.TEST_ID=TEST_QUESTION.TEST_ID
JOIN PASSED_TEST ON TEST.TEST_ID=PASSED_TEST.TEST_ID
AND TEST.VERSION_ID=PASSED_TEST.VERSION_ID
WHERE TEST.SUBJECT_ID = ?
AND PASSED_TEST.USER_ID = ?
GROUP BY PASSED_TEST.TEST_EVENT_ID
]]>
</sql-query>
そしてDAO
return session
.createSQLQuery(GET_ARRAY_MAX_POINT_QUESTION_NAME_QUERY)
.addScalar(TEST_ID_RESULT_PARAM, StandardBasicTypes.LONG)
.addScalar(VERSION_ID_RESULT_PARAM, StandardBasicTypes.LONG)
.addScalar(USER_RESULT_PARAM, StandardBasicTypes.DOUBLE)
.addScalar(MAX_TEST_RESULT_PARAM, StandardBasicTypes.DOUBLE)
.addScalar(TIME_COMPLITED_RESULT_PARAM, StandardBasicTypes.DATE)
.setParameter(0, subjectId)
.setParameter(1, userId)
.setResultTransformer(
Transformers.aliasToBean(PassedTestStatistic.class))
.list();
私はそれを読み、//JPA specification. Only positional parameter binding may be portably used for native queries.
その休止状態は最初のインデックスとして0を使用します。

//アップデート
興味深いことに、クエリの数値を設定すると
WHERE TEST.SUBJECT_ID = 1
AND PASSED_TEST.USER_ID = 1
私は得る
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'GET_ARRAY_MAX_POINT_QUESTION' at line 1
しかし、MySQL では成功した結果が得られます。
どうすればこの問題を解決できますか?
