JPA SQL Server No Dialect mapping for JDBC type: -9
Iam writing a native query like
Query query =
entityManagerUtil.getEntityManager().createNativeQuery("SELECT c.NodeID,c.Code,c.Name FROM COM_Location c");
query.getResultList();
but it is not working for me....
Iam using JPA , MSSQL Server 2008 with Spring.It is working fine when i try to write JPA queries with pojo classes but it is failing to execute native queries.
My configurations in persistance.xml goes like this
<property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>
Any one suggest me to fix the issuee
My stack trace says...

First you have to define what is your dialect class name that you want to use: in hibernate.cfg.xml add your own class address
<property name="hibernate.dialect">com.nhl.dao.SQlServerDBDialect</property>
then create new class same below
package com.nhl.dao;
import java.sql.Types;
import org.hibernate.dialect.SQLServerDialect;
import org.hibernate.type.StandardBasicTypes;
public class SQlServerDBDialect extends SQLServerDialect {
public SQlServerDBDialect() {
super();
registerHibernateType(Types.NCHAR, StandardBasicTypes.CHARACTER.getName());
registerHibernateType(Types.NCHAR, 1, StandardBasicTypes.CHARACTER.getName());
registerHibernateType(Types.NCHAR, 255, StandardBasicTypes.STRING.getName());
registerHibernateType(Types.NVARCHAR, StandardBasicTypes.STRING.getName());
registerHibernateType(Types.LONGNVARCHAR, StandardBasicTypes.TEXT.getName());
registerHibernateType(Types.NCLOB, StandardBasicTypes.CLOB.getName());
}
}
The type -9 is java.sql.Types.NVARCHAR. Looking at the sources of the SQLServerDialect variants on https://github.com/hibernate/hibernate-orm/tree/master/hibernate-core/src/main/java/org/hibernate/dialect there is no mapping for nvarchar columns.
You might want to try to define your own dialect that also registers various NVARCHAR-like definitions:
public class SQLServer2008DialectWithNvarchar extends SQLServer2008Dialect {
public SQLServer2008DialectWithNvarchar () {
registerColumnType( Types.NCLOB, "nvarchar(MAX)" );
registerColumnType( Types.LONGNVARCHAR, "nvarchar(MAX)" );
registerColumnType( Types.NVARCHAR, "nvarchar(MAX)" );
registerColumnType( Types.NVARCHAR, 4000, "nvarchar($1)" );
}
}
I based this on the definition for VARCHAR in the SQLServer2005Dialect. You may need to put this class in the org.hibernate.dialect package (or at least I seem to remember there are issues if you don't).
NOTE: I haven't actually tested this!
I also face the same issue, So i do R&D and got solution as Do explicit cast like cast(t2.name as varchar), It works for me.
cast(t2.name as varchar)
Check this url. http://www.coderanch.com/t/565413/ORM/databases/Dialect-mapping-JDBC-type
I had a similar issue, my sql is this
Query nmspQuery = em.createNativeQuery("select aster from MyTable where my_column = 1001")
The datatype for PRODUCT_NODE_ONIX_TYPE in the Oracle 11g is nvarachar2
I fixed it by casting the value astr to to_char. This worked fine
Query nmspQuery = em.createNativeQuery("select TO_CHAR(aster) from MyTable where my_column = 1001")
You have to extend the dialect, and register the appropriate Hibernate types for the N* JDBC types, in the constructor:
public class MyDialect extends SomeOfTheProvidedDialects {
public MyDialect() {
registerHibernateType(Types.NCHAR, StandardBasicTypes.CHARACTER.getName());
registerHibernateType(Types.NCHAR, 1, StandardBasicTypes.CHARACTER.getName());
registerHibernateType(Types.NCHAR, 255, StandardBasicTypes.STRING.getName());
registerHibernateType(Types.NVARCHAR, StandardBasicTypes.STRING.getName());
registerHibernateType(Types.LONGNVARCHAR, StandardBasicTypes.TEXT.getName());
registerHibernateType(Types.NCLOB, StandardBasicTypes.CLOB.getName());
}
}
Tested, works fine.
They should have added these to the Hibernate source code already (in the org.hibernate.dialect.Dialect class)...
