The previous response had some junk at the end that I meant to delete ...
Brent,
It looks like I have not been thinking this all the way through. Since
you have fixed the case where a generated key column is present then
lets consider the case where one is not. It seems our choices here are
to either throw an exception -- this is likely an error condition -- or
to attempt an empty INSERT since that is what we are being asked to do.
What do you think?

Kevin,
I'm not sure what behavior you want here. The ID column in your test
case is not a generated column. How do you want the DAS to pick an ID
value? The issue with doing an empty insert with a generated ID
column was fixed in tuscany-957.
ApplyChnages fails when added DO does not include a modified property
---------------------------------------------------------------------
Key: TUSCANY-1007
URL: http://issues.apache.org/jira/browse/TUSCANY-1007
Project: Tuscany
Issue Type: Bug
Reporter: Kevin Williams
Looks like the generated insert is invalid when the change history
for an added DO does not include a modified property. I think the
correct behavior should be to generate an ID-only INSERT. An
alternative would be to generate an INSERT that initializes all
columns ... i'd be interested in hearing arguments to justify the
latter.
This test:
/das/src/test/java/org/apache/tuscany/das/rdb/test/CrudWithChangeHistory.testReadInsertApply()
demonstrates the problem. I have temporarily commented it out.
Here is the stack trace:
java.lang.RuntimeException: SQL Exception: Column 'ID' cannot
accept a NULL value.
