I am not able to display the bmp stored in the
BFILE.I followed the following steps.I have been following the
NOTE from metalink and the oracle app dev
guide.
CREATE TABLE empbfiles (id NUMBER PRIMARY KEY,
empname
VARCHAR2(20),
photo BFILE); / CREATE OR REPLACE DIRECTORY empbfiles AS '/u02/ora'; /
INSERT INTO empbfiles VALUES (1,
'Smith',bfilename('EMPBFILES', 'smith.bmp'));
/
select count(*) from empbfiles where
id=1;
/
COUNT(*) ---------- 1 I am using the following procedure(got this from
the oracle app devlopers guide) to display the bfile data
CREATE OR REPLACE PROCEDURE displayBFILE_proc
IS
Lob_loc BFILE; Buffer RAW(1024); Amount BINARY_INTEGER := 1024; Position INTEGER := 1; BEGIN /* Select the LOB: */ SELECT photo INTO Lob_loc FROM empbfiles WHERE id = 1; /* Opening the BFILE: */ 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 LOOP; /* Closing the BFILE: */ DBMS_LOB.CLOSE (Lob_loc); END; when I execute the above procedure I am getting the
following error
ERROR at line 1:
ORA-01403: no data found ORA-06512: at "SYS.DBMS_LOB", line 656 ORA-06512: at "HHNEWBUILD.DISPLAYBFILE_PROC", line 13 ORA-06512: at line 1 What am i missing or doing wrong.
