Hi, all. I'm a prospective student for GSOC, Yun Lee. I have posted a patch
for this issue, wish for your comments.
At this moment, I'm in the user group, without the permission to assign this

Thanks!
> Clob.truncate(0) throws exception

> Key: DERBY-3991
> URL: https://issues.apache.org/jira/browse/DERBY-3991
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.3.3.1, 10.4.2.1, 10.5.0.0
> Reporter: Kristian Waagan
> Priority: Minor
> Attachments: derby-3991-1a-ClobTruncateZeroTest.diff,

>
> 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.
