我已经尝试了很多方法来调用一个简单的存储过程来进行休眠,而且无法找到一种方法。
我有一个返回本地表变量的过程:
SET NOCOUNT ON
declare @tableTemp Table
(
ID int,
Tipo nvarchar(50),
Regra nvarchar(50),
Quantidade int
)
select * from @tableTemp
我的疑问是:
Query query = em.createNativeQuery("{call GetEstatisticasDeRegras}");
List result = query.getResultList();
我一直收到错误:
javax.persistence.PersistenceException: org.hibernate.MappingException: **No Dialect mapping for JDBC type: -9**
alredy尝试过:
*致电GetEstatisticasDeRegras
* exec GetEstatisticasDeRegras
*执行GetEstatisticasDeRegras
* {call GetEstatisticasDeRegras}
* exec dbo.GetEstatisticasDeRegras
但不是这样。我的用户对该程序有所有特权。
修改
我的persistence.xml:

对此有何帮助?
答案 0 :(得分:0)
发生此错误是因为hibernate不知道如何将nvarchar
数据库类型映射到java类型。您需要定义Dialect
。假设您使用sqlserver2008,您可以像这样定义Dialect
public class MsSqlDialect extends SQLServer2008Dialect {
public MsSqlDialect(){
super();
registerHibernateType(Types.NVARCHAR, "string");
}
}
然后将hibernate.dialect
修改为您自己的
<property name="hibernate.dialect" value="xxx.xxxx.MsSqlDialect" />
