Kathey Marsden updated DERBY-6214:
----------------------------------
Priority: Major (was: Critical)
Issue & fix info: Repro attached,Workaround attached
According to this reference chart 8.9.5, I was surprised to find that
setObject of a String to a Clob is not marked as something that should work.
http://docs.oracle.com/javase/6/docs/technotes/guides/jdbc/getstart/mapping.html
We do have a history of it working in some contexts so it seems to make sense
to fix this case to work the same way, but makes sense to bring down the
priority especially since there is a work around. I am done with the work I
plan to do on this issue.

> Project: Derby
> Issue Type: Bug
> Affects Versions: 10.8.3.0, 10.9.1.0

> The issue is specific to the DerbyNet client driver, and doesn't seem to
> occur using embedded Derby.
> "PreparedStatement.setObject(int, Object, Types.CLOB)". It seems to be a
> problem updating a CLOB column with a parameterized value using the DerbyNet
> client driver, and if the update SQL ends up updating more than one row. I
> attached a simple test case that just uses JDBC to reproduce the error. The
> exception looks like this:
> org.apache.derby.client.am.BatchUpdateException: Non-atomic batch failure.
> The batch was submitted, but at least one exception occurred on an individual
> member of the batch. Use getNextException() to retrieve the exceptions for
> specific batched elements.
