Hi dwolvert ,
         Please explain why it is invalid defect, I already check with org.hibernate.criterion.Restrictions class , we can use Restrictions -> eqProperty (p1,p2) compares two columns of table. at least this functionality should be there.

abhijitbanke,

Hi. Sorry. The reason is because the framework actually does have this feature. 
If you post to the group then others who have the same question will be able to 
see the answer.

Here's how it's done:

search.addFilterCustom("{p1} < {p2}");

see 
http://hibernate-generic-dao.googlecode.com/svn/trunk/docs/api/com/googlecode/ge
nericdao/search/Filter.html#custom%28java.lang.String%29

That said, we really do have a "defect" in our documentation, because this 
custom filter feature has not been added to the documentation on the 
wiki--which is a major flaw.
