If u're working with JDBC then u should just open the OutputStream of the
BLOB and write content from the .wav file's InputStream there.
If u want to do it only with the help of the DBMS_LOB package then you could
take a look in the docs in the "Oracle8i
Application Developer's Guide - Large Objects (LOBs) " chapter. There is an
example for reading a file and storing the content into a BLOB that looks
like :
/* Note that the example procedure loadLOBFromBFILE_proc is not part of the
DBMS_LOB package: */
CREATE OR REPLACE PROCEDURE loadLOBFromBFILE_proc
IS
Dest_loc BLOB;
Src_loc BFILE := BFILENAME('FRAME_DIR', 'Washington_frame');
Amount INTEGER := 4000;
BEGIN
SELECT Frame INTO Dest_loc FROM Multimedia_tab
WHERE Clip_ID = 3 FOR UPDATE;
/* Opening the source BFILE is mandatory: */
DBMS_LOB.OPEN(Src_loc, DBMS_LOB.LOB_READONLY);
/* Opening the LOB is optional: */
DBMS_LOB.OPEN(Dest_loc, DBMS_LOB.LOB_READWRITE);
DBMS_LOB.LOADFROMFILE(Dest_loc, Src_loc, Amount);
/* Closing the LOB is mandatory if you have opened it: */
DBMS_LOB.CLOSE(Dest_loc);
DBMS_LOB.CLOSE(Src_loc);
COMMIT;
END;
Of course u should read the docs for details about the example (especially
for details about CREATE DIRECTORY, BFILE, EMPTY_BLOB()).
