See more:

suppose i have a pojo like

@Entity
@Table(name = "college", catalog = "practice")

public class College implements java.io.Serializable
{

private int id;
private String name;
private String caddress;
private String ccode;
}
and getters and setters

Now i want an object of this pojo from this query

XML

SQLQuery query = session.createSQLQuery("select id,name from  College");
       query.addEntity(College.class);

       List<College> employees = query.list();

But this query will give the result in list(because i have not provided all columns)<Object[]> but i want a pojo object having the value of provided columns

How to do that........
please reply
thanks in Advance

we can take an alternate approach for that first we will fetch the result in to map and then covert to pojo by using jackson api for example

Java

SQLQuery query = session.createSQLQuery("select id,name from  College");
       query.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
 List<map><string,>> list = query.list();

for (Map<string,> map : list)
        {

          
            ObjectMapper m = new ObjectMapper();
           
            College anotherBean = m.convertValue(map, College.class);
            colleges.add(anotherBean);

            System.out.println(anotherBean);

          
        }</map>
