oracle - JDBC 类型 : -9 没有方言映射

Question

我在使用 native SQL 查询时遇到问题...

当这段代码:

SimpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
List<Object[]> objects = entityManager.createNativeQuery(" select ERROR_CODE, REASON,
count(*) " + //
" from flow_error " + //
"where timestamp " + //
" between to_date(:endDate,'YYYY-MM-DD HH24:MI:SS') " + //
" and to_date(:startDate,'YYYY-MM-DD HH24:MI:SS') " + //
" AND TRANSACTION_UUID in ( " + //
" SELECT TRANSACTION_UUID " + //
" FROM RJT_HIST " + //
" WHERE insert_tst " + //
" between to_date(:endDate,'YYYY-MM-DD HH24:MI:SS') " + //
" and to_date(:startDate,'YYYY-MM-DD HH24:MI:SS') " + //
" and flow_number = :flowNumber) " + //
" GROUP BY ERROR_CODE, REASON")//
.setParameter("endDate", sdfDatetime.format(endDate))//
.setParameter("startDate", sdfDatetime.format(startDate))//
.setParameter("flowNumber", flowNumber)//
.getResultList();

在 tomcat 服务器 v5.5 上使用，代码运行良好，不返回任何异常。 但问题出现在 weblogic 服务器 (v10.3.6) 上。 我从 hibernate 中得到一个映射异常:

我想不通为什么。
有什么猜测吗？
提前致谢。

最后的解决方案确实像org.hibernate.MappingException :No Dialect mapping for JDBC type: -9

我看错了方言。这是针对 SQLServer 的，我使用的是 Oracle10gDialect。 所以我上了这门课:

public class Oracle10gDialectOverrider extends Oracle10gDialect{

public Oracle10gDialectOverrider(){
    super();
    registerHibernateType(Types.NVARCHAR, Hibernate.STRING.getName());
}

}

并在我的 hibernate xml 中指定:Oracle10gDialectOverrider 而不是 Oracle10gDialect

谢谢
