Hi Yun,

I have added you as a contributor to the Derby project. This should give 
you the permission you need. Here's a good primer on getting started as 
a Derby developer: http://db.apache.org/derby/derby_comm.html I don't 
think that Apache has an ICLA on file for you yet. The contributor 
checklist points you at the instructions for filing an ICLA so that 
Apache can accept your contributions: 
http://wiki.apache.org/db-derby/DerbyContributorChecklist

Welcome to the Derby developer group!
-Rick

>> Truncating a Clob to zero length is allowed according to the JDBC specification, which says the following about the len argument (in the @throws tag):
>> "SQLException - if there is an error accessing the CLOB value or if len is less than 0 "
>> Derby throws an exception if zero is passed to truncate.
>> A quick inspection of the code suggests that truncating a Clob to the empty string is easy to support.
