JDBC LOB . getBtypes methods are not implemented in any Derby version to date:
there is a "place-holder" method that throws a SQLException reporting that the
methods are not implemented.
It would be excellent to have any efficient Derby implementation of the
getBytes LOB methods that provide "random-access" to the binary // character
content of database large objects. The specific context is implementing a
Lucene Directory interface that stores indexing data (index files) and other
binary data in a local encrypted Derby instance.
A work around is to write an encrypted RandomAccessFile implementation as a
file-sdystem buffer, perhaps writing to the database on closure. An efficient
Derby implementation of LOB . getBytes would avoid this an make for a clean
design. I can think of several reasons why random-access to LOBs would be
valuable in a "hostile" client environment.
