--------------------------------------
Can you post a testcase which exhibits this behavior that you're referring to?
> Update statements should not update the primary key of database unless the
> primary key has in fact changed

> Key: OPENJPA-2263
> URL: https://issues.apache.org/jira/browse/OPENJPA-2263
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 2.2.0
> Reporter: garpinc
>
> 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.
