HI, Thanks Justin Cave & Subodh! Justin your suggestion to use put_raw helped. Moreover when I open the file thru utl_file.fopen, the maxlinesize was default(1000 bytes) this gave file write error, I changed it to the max(32767), this also helped to solve it. Now, my source of my image file(tif) is 36130 bytes, when I read and load into Oracle its still 36130 bytes, I checked using dbms_lob.getlength(blob_obj). 10:40:04 SQL> SELECT dbms_lob.getlength(blob_obj) from thiagu; DBMS_LOB.GETLENGTH(BLOB_OBJ) ---------------------------- 36130 1 row selected. But, when I read this TIF file and write in a different file, it's one byte more 36131 bytes. How can I resolve this? The code which I used to read from DB is:- ====Code Starts here===== CREATE OR REPLACE PROCEDURE retrieve_blob IS temp_blob BLOB; data_buffer RAW (1); temp_buffer VARCHAR2(1); amount BINARY_INTEGER := 1; position INTEGER := 1; filehandle utl_file.file_type; error_number NUMBER; error_message VARCHAR2(100); length_count INTEGER; BEGIN SELECT blob_obj INTO temp_blob FROM thiagu WHERE id = 1; length_count := dbms_lob.getlength(temp_blob); dbms_output.put_line('Internal LOB size is: ' || length_count); filehandle := utl_file.fopen('DIR1','lob_flat.out','W',32767); WHILE length_count <> 0 LOOP dbms_lob.read (temp_blob, amount, position, data_buffer); --temp_buffer := utl_raw.cast_to_varchar2(data_buffer); utl_file.put_raw(filehandle, data_buffer); --utl_file.put(filehandle, temp_buffer); position := position + 1; length_count := length_count - 1; data_buffer := null; END LOOP; dbms_output.put_line('Exit the loop'); utl_file.fclose(filehandle); dbms_output.put_line('Close the file'); EXCEPTION WHEN OTHERS THEN BEGIN error_number := sqlcode; error_message := substr(sqlerrm ,1 ,100); dbms_output.put_line('Error #: ' || error_number); dbms_output.put_line('Error Message: ' || error_message); utl_file.fclose_all; END; END; / =====Code ends here==== SQL> execute retrieve_blob; Internal LOB size is: 36130 Exit the loop Close the file PL/SQL procedure successfully completed. -rw-r--r-- 1 uuuu gggg 36130 May 13 09:13 MER046084.tif -rw-r--r-- 1 oracle gggg 36131 May 13 10:12 lob_flat.out Thanks & Best Regards, Thiagu "Justin Cave (DDBC)" <jcave@xxxxxxxxxxx> wrote: First, error numbers and a code sample would be helpful. Second, you need to be using 9i or later to be able to read & write binary data via UTL_FILE. You also need to use the PUT_RAW function rather than using PUT. That doesn't explain the file handle error-- are you sure that you opened the file first?

Hi All, I want to load few image files into Oracle BLOB columns and later would Iike to extract it & write in a file. How to load & extract an Image(TIF) file into/from Oracle-BLOB?, am using dbms_lob.loadfromfile() to load into Oracle. I'm retrieving thru dbms_lob.read and writing using utl_file.put, I'm not able to write in a file. How can I retrieve this..?When I try to retrieve it say File Handle error. If this image file operation is successful, I have few Word/Execl files to follow-on! Any help in this regard is highly appreciated! TIA, Best Regards, THIAGU --------------------------------- Yahoo!
