[jira] [Resolved] (OPENJPA-2263) Update statements should not
update the primary key of database unless the primary key has in fact
changed
[ https://issues.apache.org/jira/browse/OPENJPA-2263?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
garpinc resolved OPENJPA-2263.
------------------------------
Resolution: Not A Problem
Fix Version/s: 2.2.0
In creating the test case I found out that OpenJPAPersistence.cast(em).dirty(wrapper, fieldName) was called on the primary key field.
I guess it's speculative whether a call like should trigger behavior like this if the field hasn't in fact changed so i've decided it's not a problem and i just did not make the primary key as dirty.

> 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.
