 Post subject: Hibernate/JPA RIGHT() function with CriteriaBuilder

How would I mimic a RIGHT() function in a query using the JPA CriteriaBuilder? I see the #length and #substring methods but I can't figure out how to do the following:
Code:
     SUBSTRING( field, LENGTH( field ) - 7 )


I'm trying to get the last 7 characters of a field for comparison. Can this be done using CriteriaBuilder or do I need to resort to a text string query expression?

TIA,

R.

Ok, found the diff and literal methods. I should have found this sooner:

Code:
   exp = builder.substring( field, builder.diff( builder.length( field ), 7 ) );
