Hi David,
Thanks for your reply. I looked at the example from AskTom.com. The
example is very helpful. I tried changing the code as given in the sample
at AskTom.com. I added owa_util.mime_header('application/pdf'); and
htp.print(utl_raw.cast_to_varchar2(v_buffer));
But now I'm getting ORA-01403: no data found error, when the browser
tries to open the PDF document in Adobe Acrobat.
v_buffer is RAW(32767);
htp.print(utl_raw.cast_to_varchar2(v_buffer)); is not working in Oracle9i
Release 2.
I highly appreciate any help or suggestions for this problem. Thanks.
Here is my updated code:
-----------------------
set define off
create or replace package search_pdfServices as
procedure showPDFDoc (p_id in numeric);
end;
/
show errors;
create or replace package body search_pdfServices as
procedure showPDFDoc (p_id in numeric) is
v_blob_selected BLOB;
v_read_amount integer;
v_read_offset integer;
v_buffer RAW(32767);
begin
select text into v_blob_selected from search_pdf_table where tk =
p_id;
v_read_amount := 32767;
v_read_offset := 1;
owa_util.mime_header('application/pdf');
begin
loop
dbms_lob.read(v_blob_selected,v_read_amount,v_read_offset,v_buffer);
htp.print(utl_raw.cast_to_varchar2(v_buffer));
v_read_offset := v_read_offset + v_read_amount;
v_read_amount := 32767;
end loop;
exception
when no_data_found then
-- null;
wwerr_api_error_ui.show_html;
end;
end showPDFDoc;
end;
/
show errors
set define on
