This contains the test case that illustrates that a dirty field will cause the pk to be updated
although it hasn't changed.. Once again this is likely expected behavior but it did give me
a bump in the road.. Test case in this is: TestCollectionValueMapper.testUpdatePk()
                
      was (Author: garpinc):
    test case to try is the testSelect0 one. When run in the console you will see the select
in the trace right after the last alter table

> I have encountered a situation while creating an openjpa dictionary for teradata. It
seems teradata does not like it when the primary key is updated. 
> i.e: update tablex set pk=1 where pk=1;
> Following the code it seems RowImpl.java contains a method getUpdateSQL which uses the
dictionary to various things but it doesn't allow the dictionary to change the statement itself.

> The specific functionality I need here is to only update the pk if the pk has changed
or maybe an option not to update the pk at all.
