thanks for the links.
I added a DN JIRA: http://www.datanucleus.org/servlet/jira/browse/NUCRDBMS-581 and attached a patch for the DerbyAdapter class. I also added a patch to the JDO JIRA https://issues.apache.org/jira/browse/JDO-682 changing the schema and the mapping to make use of sequences in derby. So the configuration detach.conf will test the DN support for sequences in derby.
Is it an issue to support sequences in the derby adapter? The derbyHi Michael,
database itself supports sequences since version 10.6.
you can easily contribute support.
The adapter for Derby at
needs updating to include support for versions 10.6+ (only).
To see an example of an adapter which has support look at
and search for "sequence" (case-insensitive); ought to give you enough of an
idea what is needed. Then raise a DN JIRA and attach a patch.
