Help selecting version column

[Jeff Melching]

I am trying to select only the version column of an entity to see if it 
was changed. 

If I run the following JPQL where verId is the version field of my entity:

select a.verId from AnEntity a where a.id = ?1;

The generated sql is: 

SELECT  FROM AN_ENTITY t0 WHERE t0.ID = ? 

Obviously, this is invalid sql syntax as the columns to select are 
missing.  I am using a DB2 dictionary.
