From "Daniel John Debrunner (JIRA)" <j...@apache.org>
Subject [jira] Commented: (DERBY-2104) Embedded - Column of type CHAR, VARCHAR or LONG VARCHAR contains wrong value after being updated using the ResultSet.updateBytes() method.
Date Mon, 27 Nov 2006 21:56:22 GMT
    [ http://issues.apache.org/jira/browse/DERBY-2104?page=comments#action_12453715 ] 
            
Daniel John Debrunner commented on DERBY-2104:
----------------------------------------------

"NEW VALUE".getBytes() will (most likely)  return a byte array that is not on the encoding
expected by Derby, thus the value stored will not map to the string "NEW VALUE".

Looking at the code I think the encoding expected by Derby for byte[] to String is UTF-16.
