java - 具有位置参数的 Hibernate native 查询

Question

我编写了原生 sql 查询而不是使用 hql 并面临问题

位置超出声明的序号参数的数量。请记住，序数参数是从 1 开始的!位置: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>

和 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();

我阅读了 //JPA 规范。只有位置参数绑定(bind)可移植地用于 native 查询。 并且 hibernate 使用 0 作为第一个索引。

//更新

有趣的是，当我设置查询数值时

WHERE TEST.SUBJECT_ID = 1
        AND PASSED_TEST.USER_ID = 1

我明白了

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 

但是在 MySQL 中我得到了成功的结果。

我该如何解决这个问题？

Answer 1

你打电话

session.createSQLQuery 

但我相信你需要打电话

session.getNamedQuery 

使用命名查询时。
