sql-server-2012 - Spring 数据 Jpa findTop 和 findFirst 生成错误 '@P0' 附近的语法不正确

Question

我正在使用 spring 数据 JPA 1.8.2 并试图获得最佳结果。我正在使用以下方法

LearningSession findTopBySourceAndExternalLmsSessionIdAndCourseCodeAndLearnerEnrollmentEnrollmentStatusOrderByIdAsc(String source, String externalLmsSessionId, String courseCode, String enrollmentStatus);

我也尝试通过删除 OrderBy

LearningSession findTopBySourceAndExternalLmsSessionIdAndCourseCodeAndLearnerEnrollmentEnrollmentStatus(String source, String externalLmsSessionId, String courseCode, String enrollmentStatus);

在这两种情况下，hibernate 都会生成以下查询。只需使用 *每件事。到底要下单 order by learningse0_.id asc

select TOP ?  learningse0_.*
from LearningSession learningse0_ 
left outer join LearnerEnrollment learnerenr1_ on learningse0_.ENROLLMENT_ID=learnerenr1_.id 
where learningse0_.source=?
and learningse0_.externalLmsSessionId=?
and learningse0_.courseCode=?
and learnerenr1_.enrollmentStatus=?

查询是正确的但我收到以下异常

Hibernate: select TOP ?  learningse0_.id as id1_47_, learningse0_.brandName as brandNam2_47_, learningse0_.courseApprovalId as courseAp3_47_, learningse0_.courseCode as courseCo4_47_, learningse0_.endTime as endTime5_47_, learningse0_.externalLmsSessionId as external6_47_, learningse0_.externalLmsUrl as external7_47_, learningse0_.isCourseMessageDisplay as isCourse8_47_, learningse0_.LANGUAGE_ID as LANGUAG15_47_, learningse0_.LEARNER_ID as LEARNER16_47_, learningse0_.ENROLLMENT_ID as ENROLLM17_47_, learningse0_.learningSessionGuid as learning9_47_, learningse0_.lmsProvider as lmsProv10_47_, learningse0_.redirectUrl as redirec11_47_, learningse0_.source as source12_47_, learningse0_.startTime as startTi13_47_, learningse0_.uniqueUserGuid as uniqueU14_47_ from LearningSession learningse0_ left outer join LearnerEnrollment learnerenr1_ on learningse0_.ENROLLMENT_ID=learnerenr1_.id where learningse0_.source=? and learningse0_.externalLmsSessionId=? and learningse0_.courseCode=? and learnerenr1_.enrollmentStatus=? order by learningse0_.id asc

我做错了什么？我试过 First , Top1 , First1但结果是错误。请帮忙。

谢谢

不确定这是否适合您，但我遇到了同样的错误，经过大量挖掘后，我发现我在 JpaVendorAdapter 中使用了 SqlServerDialect，当我将其更改为更专门用于 SqlServer2012 (SqlServerDialect2012) 时，错误走了:

<bean id="jpaVendorAdapter"
    class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
    <property name="database" value="SQL_SERVER" />
    <property name="databasePlatform" value="org.hibernate.dialect.SQLServer2012Dialect" />
    <property name="showSql" value="true" />
</bean>
