Subject [jira] Updated: (DERBY-1421) ResultSet.updateBinaryStream fails when the result type is TYPE_SCROLL_INSENSITIVE
Date Wed, 21 Jun 2006 07:55:31 GMT
     [ http://issues.apache.org/jira/browse/DERBY-1421?page=all ]

Fernanda Pizzorno updated DERBY-1421:

    Attachment: derby-1421.diff

ResultSet.updateBinaryStream() fails for scrollable updatable result sets because of a call
to the method ExecRow.clone() that fails. When the clone method in the SQLBinary column is
called, the stream has already been read and is closed, and an attempt to read this closed
stream causes an exception. The streams used in this case are of type RemeberBytesInputStream.
This type of stream keeps a copy of every byte that has been read or skipped, and can be re-read
using a "replay" stream.

This patch (derby-1421.diff) fixes this problem by using the "replay" stream to get the data,
if the stream has previously been read. I have successfully run derbyall with this patch.
Can someone please review it?

Thank you in advance.
