Hibernate version: 2.17

I am trying to introduce the Hibernate with our existing system. One of the existing components needs data in a result set while the data i am getting from Hibernate is object. My question is how can I do it ? Even if I write a SQL query and call it through session.createSQLQuery() method, I got objects as the Hibernate book says on Page 242 :

there is direct SQL with automatic mapping of result sets to objects.

I want it the other way around. Any input?

Thanks

The main purpose of useing an ORM tool is, that you don't have to deal with things like resultsets. If your application deals with resultsets and (prepared)statements already you're maybe better of looking for a framework which makes the JDBC handling easier. (Have a look at Spring).

If you need the resultset only in some rare cases you can always get the current connection (Session.connection()) and do all the JDBC sutff yourself. If you do update/delete/insert calls to the db be carfull, since hibernate doesn't know anything about your operations and may get out of sinc with the db.

You are right about resultset. But we cannot discard the old code right away. We will be fixing the old code gradually. But for now we have to find workaround. Fortunately we need resultset like that in rare cases.

To pass resultset we use a RowSetAdaptor class :

import java.io.Serializable;
import java.sql.ResultSet;
import com.sun.rowset.CachedRowSetImpl;

public class RowSetAdaptor implements Serializable {
private CachedRowSetImpl rowset;
public RowSetAdaptor() {
try {
rowset = new CachedRowSetImpl();
}
catch( Exception e ){
System.out.println( "RowSetAdaptor: constructor --> " + e.getMessage() );
e.printStackTrace();
}
}

public void populate( ResultSet data ) {
try {
rowset.populate(data);
}
catch( Exception e ){
System.out.println( "RowSetAdaptor: populate --> " + e.getMessage() );
e.printStackTrace();
}
}
...
}

I was thinking about using ScrollableResults of Hibernate and translating it into RowSetAdaptor. Is it possible?

thanks
