• Hibernate가 MS SQLServer의 NVARCHAR를 인식하지 못하는 문제 발생시 아래 오류 발생

  org.hibernate.MappingException: No Dialect mapping for JDBC type: -9

• MS SQL Server에서 JPA NativeQuery 사용시 유니코드(Unicode) 문제
• java - JPA SQL Server No Dialect mapping for JDBC type: -9
• Getting Hibernate and SQL Server to play nice with VARCHAR and NVARCHAR - QuestionFocus
• SQLServer2008Dialect에서 NVARCHAR registerColumnType 돼 있음

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());
 
} }

• registerHibernateType은 Hibernate Dialect 참조
• @org.hibernate.annotations.Nationalized 애노테이션을 통해 NVARCHAR 로 Entity Column 매핑을 할 수 있다.
