public class Part{
private Integer id;

names after join.
I am sure it is not correct way to do it. Please advice how to do
Hi,
I have customer registration web application. Where it takes 3 pages to

Why don't you override the Object.hashcode() method on your VO
and call it and save the value when you retrieve the record. Call it
again when the user submits their changes.
If the values are different, the a change was made.

No I think. iBatis is not aware whether your VO-s have changed and can not

Thanks for your reply. I would like to clarify my understanding about what
you have mentioned.
Here is one of my VO generated thru JDeveloper IDE, it has both equals()
and hashCode() methods overriden. So now to you point, I can use equals()
method too? right? But I still have to
If you override equals, you have to have two VO objects to do the
comparison.
I think it is better to perform this type of work in one of your
business or service methods. You could then let your user know if
anything was updated.

Just an FYI, if you override equals(), you should almost always override
hashcode as well. From the Object.equals Javadoc API:
Note that it is generally necessary
So only way is to do with aliases?
No way I can reuse the already mapped dto other then remap it?

You can use the select attribute instead of resultMap. You can combine
this with lazy loading.
