Rick Hillegas updated DERBY-3155:
---------------------------------
Attachment: derby-3155-39-aa-fixBuild.diff
Thanks for spotting that, Knut. Attaching derby-3155-39-aa-fixBuild.diff. This
fixes the build problem. I'm also introducing a new Blob-making method for my
next batch of tests.
I have verified that the build fails on Java 7 without this fix, but works with
this fix.

> A relatively common piece of logic in a database application is to check for
> a row's existence and then either update or insert depending on its existence.
> SQL:2003 added a MERGE statement to perform this operation. It looks like
> this:
> MERGE INTO table_name USING table_name ON (condition)
> WHEN MATCHED THEN UPDATE SET column1 = value1 [, column2 = value2 ...]
> WHEN NOT MATCHED THEN INSERT column1 [, column2 ...] VALUES (value1 [,
> value2 ...])
> At the moment, the only workaround for this would be to write a stored
> procedure to do the same operation, or to implement the logic client-side.
