Good morning, I have a query with:

SQLQuery queryDatosPoliza = getSession(false).createSQLQuery("Select ...");

queryDatosPoliza.setString(0, code);
queryDatosPoliza.setString(1, company);
Object[] datosGeneralesPoliza = (Object[]) queryDatosPoliza.uniqueResult();


And I receive the error No Dialect mapping for JDBC type: -100, We have a Oracle Data base and the hibernate's properties are:

<property name="hibernateProperties">
<props>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>
<prop key="hibernate.cache.use_query_cache">false</prop>
<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
<prop key="hibernate.cache.query_cache_factory">org.hibernate.cache.StandardQueryCacheFactory</prop>
</props>
</property>

Any ideas? why= the dialect is the correct and in others PC's this run.

Regards.

I discover that the problem are fields TimeStamp, not mapping¡ why???....
