我正在尝试使用 sqlserver 2008 作为 DB 将应用程序从 jboss 4.2.3 移植到 7.1.1，当我在 persistence.xml 中将方言从 org.hibernate.dialect.SQLServerDialect 更改为 2008 方言时遇到了问题。对于以前版本的方言，我遇到了分页问题，​​为此提供了更改方言作为解决方案。从我分析的日志来看，一些额外的语句是自动添加的。

版本详情如下

16:46:10,844 INFO  [org.hibernate.annotations.common.Version] (MSC service thread 1-5) HCANN000001: Hibernate Commons Annotations {4.0.1.Final}

16:46:11,934 INFO  [org.hibernate.validator.util.Version] (MSC service thread 1-5) Hibernate Validator 4.2.0.Final

实际查询是 

select proj.proj_id,count(distinct projbid.user_id)  as numRespondents,c.customer_name,proj.campaign_id from  customer c,proj left join  projbid ON  (projbid.proj_id = proj.proj_id AND projbid.bid_status in (2, 5)) where proj.spec_id=spec.spec_id and proj.userid= :userId and proj.int_client_id=c.customer_id and proj.proj_state= :projState group by proj.proj_id, c.customer_name,proj.campaign_id  order by proj.job_id ASC

JPA/Hibernate 使用的查询是

**I am getting the exception as below** 

16:47:39,262 WARN  [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (http-localhost-127.0.0.1-8080-2) SQL Error: 156, SQLState: S0001
16:47:39,264 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (http-localhost-127.0.0.1-8080-2) Incorrect syntax near the keyword 'group'.

我可以看到 groupby 被添加了多次，并且执行的 java 代码片段如下

results = em.createNativeQuery(selectSql.toString()).setParameter("userId", userId).setParameter("projState", 2).setMaxResults(param.getPageSize()).setFirstResult(param.getStart()).setHint("org.hibernate.readOnly", true).getResultList();

任何帮助将不胜感激。

AS 7.1.1.Final 附带的休眠中存在一个错误。前段时间已修复。您可以通过以下方式解决此问题

  • 使用更新版本的 AS，我会推荐 7.2.0.Final（作为 EAP 6.1.Alpha 发布）
  • 手动将hibernate升级到4.2.x系列的最新版本（目前是4.2.6.Final）
  • 通过将方言设置为 SQLServer2005 的解决方法，其行为与 2008 基本相同

短期内我只会将方言更改为 2005 一种或将 AS 升级到 7.2
