Subject [jira] [Created] (OPENJPA-2263) Update statements should not update the primary key of database unless the primary key has in fact changed
Date Wed, 19 Sep 2012 22:54:07 GMT
garpinc created OPENJPA-2263:
--------------------------------

             Summary: 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.
