带位置参数的Hibernate本机查询

Question

我写了原生sql查询，而不是使用hql和面对roblem

超出声明序数参数的位置。记住序数参数是基于1的！职位： 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();

我读了//JPA规范。只有位置参数绑定可移植地用于本机查询和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。

我如何决定这个问题？

Answer 1

您可以尝试使用命名参数而不是提供位置参数吗？

例如。

session
  .createSQLQuery("update table1 set variable = variable + 1 where id = :id")
  .setParameter("id", someId)
  .executeUpdate();

本机SQL查询支持位置参数和命名参数。

请阅读命名SQL查询：http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/querysql.html#d0e13930

Answer 2

请检查一下

.setParameter(1, subjectId)
.setParameter(2, userId)

正如异常跟踪所说，序号参数是基于1的！

Answer 3

你打电话

session.createSQLQuery 

但我相信你需要打电话

session.getNamedQuery 

当使用命名查询时。
