Question

So I’m going to be using Flex 4 with Spring and Hibernate.
Everything is configured and working. I know this as I can do simple queries, like listing all values in a table.
Problem is when I try to perform a ‘select’ query, then I get all the values, as I was getting before, and not the specific attributes through Select query.

I’m a beginner, so kindly overlook my lack of more technically sound words..but I don use them as I don wanna mis-quote.

Following is some code which will make You understand things better:
This is class used to store data coming from the MySQL database–

package flex;


import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;



@Entity
@Table(name="intrial1")
public class intrial1 implements Serializable {

    @Id @GeneratedValue
    @Column( name = "id")
    private int id;
    @Column( name = "name")
    private String name;



    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }


    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    }

This is the class where the sessionFactory does things(too many import statements, just to try to make things work-ignore)–

package flex;

import java.util.ArrayList;
import java.util.List;


import javax.persistence.Query;
import org.hibernate.SessionFactory;
import org.hibernate.annotations.NamedNativeQueries;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.flex.remoting.RemotingDestination;
import org.springframework.flex.remoting.RemotingInclude;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;



import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import org.springframework.transaction.annotation.Transactional;




@Repository
@RemotingDestination
public class SpringBean_Service  {


    private SessionFactory sessionFactory;

    @Autowired
    public void setSessionFactory(SessionFactory factory) {
        sessionFactory = factory;
    }

    @SuppressWarnings("unchecked")
    @RemotingInclude
    @Transactional
    public List<intrial1> getList() {

        return sessionFactory.getCurrentSession().createQuery("from intrial1 ").list();
    }

    @SuppressWarnings("unchecked")
    @RemotingInclude
    @Transactional
    public List<intrial1> getListAgain() {



        org.hibernate.Query q = sessionFactory.getCurrentSession().createQuery("select id from intrial1 where name='chirayu'");
        List l = q.list();
        return l; 


    }


    @RemotingInclude
    @Transactional
    public void createFriend(String name, int id) {
        intrial1 f = new intrial1();
        f.setName(name);
        f.setId(id);
        sessionFactory.getCurrentSession().save(f);

}
}

In above class, getList() works
perfect, lists all the values. The
createFriend is used to enter values
of id+name, and works smoothly. The
problem is with getListAgain()
function, it gives me a result,
imagine 2 columns, having heading as
‘id’ and ‘name’, but listing id values
in both the columns (No names), As You
can understand, I am looking for
result of getListAgain() function as –
“1 column having header as ‘id’, and
listing id wherever the name
=’chirayu'”.

Kindly help, as I will need to clear this and move ahead with development.
Thank You.

Chirayu

UPDATE NOTE: Would like to say one thing here, if only I make a class as below, which is identical to intrial1 class, but has no return statement for name, i.e., no getName() defined, I get my correct result for the query –

‘select id from intrial1 where
name=’chirayu”

package flex;


import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;



@Entity

public class intrial2 {

    @Id @GeneratedValue
    @Column( name = "id")
    private int id;
    @Column( name = "name")
    private String name;




    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }


    public void setName(String name) {
        this.name = name;
    }

    }

Is this strange or meant to be like this. Still looking for answers.

Answer 1

The query

select id from intrial1 where name='chirayu'

doesn’t return intrial1 entity, so you should change return type to List or simply change your query to:

from intrial1 where name='chirayu'
