Suresh Thalamati updated DERBY-378:

DERBY-378 (partial)
This patch adds code to handles NULL (SQL NULL) data while
performing import/export of table with column types blob, clob.
Checks for invalid hex strings in the import file while performing
import into a table with Blob column. Import will throw an exception
if it detects any invalid hex strings in the import file for blob column.
Tests:
1) Added a new junit test ImportExportLobTest.java to
tests import/export of clobs and blob data.
2) Wrapped BufferInputStream/BufferedReader around the streams
used in BaseJDBCTestCase.java:assertEquals() methods to compare
clobs/blobs. Without buffering these assert method were really slow.
> support for import/export of tables with clob/blob and the other binary
> data types will be good addition to derby,
