即使我使用正确的映射在HQL中提供类和实体名称，Hibernate中的querysyntaxexception

Question

I am working on a hibernate. I am getting below Exception

org.hibernate.hql.ast.QuerySyntaxException: DBCDataSource is not mapped [from DBCDataSource where upper(datasourceType) = upper('BAC_MANAGEMENT')]

I searched in net and got answer as in HQL we need to use class names and property names instead of table and column names. The query was using column name so i have changed it ti use property name after that also exception dint went. I have checked in HIbernate.cfg.xml the for any missing mapping but i found mapping s correct. Find ma code below.

previous query-->list =  session.createQuery("from DBCDataSource where upper(DATASOURCE_TYPE) = upper('" + type +"')").list();
DATASOURCE_TYPE is a column name

Modified to-->list =  session.createQuery("from DBCDataSource where upper(datasourceType) = upper('" + type +"')").list();
datasourceType is a propery name mapped to tat column.

Entity class

@Entity
@Table(name="dict_db_ds")
public class DBCDataSource implements Serializable{
.
.
.

@Column(name = "DATASOURCE_TYPE")
    private String datasourceType;

}

Hibernate.cfg.xml

..
..
 <mapping class="com.hp.bto.bsmr.collection.dao.omi.DBCDataSource" /> 
..
..

am i missing further??

Kindly advice..

Thank you.

You can try this

 list =  session.createQuery("from DBCDataSource where "
              +"upper(datasourceType) =:type")
             .setParameter("type", type)
             .list();
