Hi All,
I want to load PDF files into the database and view the content of the lobs column. Below is what I did step by step. Anyone please point out what did I do wrong in my procedure. I am still unable to view the content of the Lobs column. I need you all for your help.
Please note that I already stored the PDF file (‘6117cdsapx.pdf’) on my Oracle server site at /Disk05/test
CREATE TABLE MY_BOOK_TEXT (
FILE_DESC VARCHAR2 (200),
BOOK_FILE BFILE);
CREATE DIRECTORY TEST AS ‘/Disk05/test’;
DECLARE
pdf BFILE;
BEGIN
pdf := BFILENAME (‘TEST’, ‘6117cdsapx.pdf’);
END;
INSERT INTO MY_BOOK_TEXT (FILE_DESC, BOOK_FILE )
VALUES (‘IBM Microprocessor’, BFILENAME(‘TEST’, ‘6117cdsapx.pdf’);
CREATE OR REPLACE PROCEDURE displayLOB_proc IS
Lob_loc BLOB;
Buffer RAW(1024);
Amount BINARY_INTEGER := 1024;
Position INTEGER := 1;
BEGIN
/* Select the LOB: */
SELECT m.Map_obj.Drawing INTO Lob_loc
FROM Multimedia_tab m WHERE m.Clip_ID = 1;
/* Opening the LOB is optional: */
DBMS_LOB.OPEN (Lob_loc, DBMS_LOB.LOB_READONLY);
LOOP
DBMS_LOB.READ (Lob_loc, Amount, Position, Buffer);
/* Display the buffer contents: */
DBMS_OUTPUT.PUT_LINE(utl_raw.cast_to_varchar2(Buffer));
Position := Position + Amount;
END LO!
OP;
/* Closing the LOB is mandatory if you have opened it: */
DBMS_LOB.CLOSE (Lob_loc);
EXCEPTION
WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.PUT_LINE('End of data');
End;
/
Thank you all for your help in advance
