Question

I have a search.jsp page where I search & retrieve a record from Database. I have to duplicate this record and make modifications and save both records.

Ex:

 method1(){
  Response response=new Response();
  //To perform DB search
  response=delegate.requestSearch(//some request criteria);
  Types obj1=(Types) response.getBaseEntity();
  Types obj2=obj1;
  obj2.setPromaryKeyObject(//some unique value);
 }

In my DAO, save method:

session.save(obj1);
session.save(obj2);
transaction.commit(); // transaction

When the debug point commits transaction, I get one update query only. But I expect two insert queries.

But this works fine. This was an attempt but this is not what I want to do.

Types tempObj1 = new Types();    
tempObj1.setValue1(obj1.getValue1();
 // all values of the object should be set
session.save(tempObj1);
Types tempObj1 = new Types();    
tempObj2.setValue1(obj2.getValue1();
 // all values of the object should be set
session.save(tempObj2);
transaction.commit(); // transaction

In this case I trigger two insert queries.

I’m pretty sure that the mistake is in my hibernate method as I’m very new to Hibernate. This same code works fine when I was using JDBC and MySql queries.

Answer 1

This is due the obj2 == obj1. Try to obj2 = obj1.clone();
