休眠执行Sql Server过程

Question

I have tried a lot of ways to call a simple stored procedure com hibernate and couldn´t just find a way to that.

I have a procedure that return a local table variable:

SET NOCOUNT ON
declare @tableTemp Table
(
    ID int,
    Tipo nvarchar(50),
    Regra nvarchar(50),
    Quantidade int
)

select * from @tableTemp

And my query is:

Query query = em.createNativeQuery("{call GetEstatisticasDeRegras}");
List result =  query.getResultList();

I keep getting the error:

 javax.persistence.PersistenceException: org.hibernate.MappingException: **No Dialect mapping for JDBC type: -9**

Have alredy tried:

*call GetEstatisticasDeRegras

*exec GetEstatisticasDeRegras

*execute GetEstatisticasDeRegras

*{call GetEstatisticasDeRegras}

*exec dbo.GetEstatisticasDeRegras

But not way. My user has all privilages over the procedure.

My persistence.xml:

            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.hbm2ddl.auto" value="update" />
        </properties>
    </persistence-unit>
</persistence>

Any help with this?

Answer 1

This error occurs because the hibernate does not know how to mapping nvarchar database types to java type. You need to define your Dialect . Suppose that you use sqlserver2008, You can define Dialect like this

public class MsSqlDialect extends SQLServer2008Dialect {
    public MsSqlDialect(){
        super();
        registerHibernateType(Types.NVARCHAR, "string");
    }
}

Then modify hibernate.dialect to your own

<property name="hibernate.dialect" value="xxx.xxxx.MsSqlDialect" />
