Kathey Marsden updated DERBY-4015:
----------------------------------
Attachment: updatedBehaviorMatrix.txt
Attached is an updated matrix. It includes JCC->DB2 and also makes some
corrections from the original matrix where we do not get an empty ResultSet but
rather get the generated key. It also adds the case where we specify a
non-generated column.
Based on this I propose we make the following changes to the network driver to
remove any perceived regression in 10.3:
Change the emptyArray case to return the generated key. This will match
embedded and can be interpreted as a case where the columns are not specified.
Change the nullParam case to return the generated key. This will match the
network client 10.3.2.1 behavior again with the logic being that it is simply a
case where the columns are not specified so the key should be returned.
These changes would be backported to 10.4/10.3 and then we would file a
separate issue for the remaining client/embedded differences which can be
addressed in the trunk.
Sorry I keep switching back and forth on this, but I think I have at least
settled my mind on a sensible solution for 10.3. Let me know what you think.

> Project: Derby
> Issue Type: Bug
> Components: Network Client
> Affects Versions: 10.3.3.0
> Environment: I am currently running on Mac 10.5 with Java 5. However,
> it has also been observed on other platforms in our automated build such as
> SUSE Linux and Windows with Java 5.
> Reporter: Brandon Smith
> Priority: Critical

>
> The application of both DERBY-2653 and DERBY-3426 in the 10.3.3.0 seems to
> have created a regression in how the network JDBC client implementation of
> PreparedStatement.getGeneratedKeys() behaves as compared to 10.3.2.1. Note
> that there wasn't a change in behavior between versions for the embedded
> implementation. However, in general there are behavior discrepancies between
> the network and client implementations for this method.
