How to show an uploaded excel file in an Iframe

Question

I like to show an excel file which is stored in the database as an excel application within the HTMLDB application. How can I do this.
Thanks,
Fred.

Answer 1

I have found the solution.
I have changed the custom table procedure from the howto upload/download application document the following way: (changes are bold)
CREATE OR REPLACE PROCEDURE download_my_file(p_file in number) AS
        v_mime  VARCHAR2(48);
        v_length  NUMBER;
        v_file_name VARCHAR2(2000);
        Lob_loc  BLOB;
BEGIN
        SELECT MIME_TYPE, BLOB_CONTENT, name,DBMS_LOB.GETLENGTH(blob_content)
                INTO v_mime,lob_loc,v_file_name,v_length
                FROM wwv_flow_file_objects$
                WHERE id = p_file;
              -- set up HTTP header
                    -- use an NVL around the mime type and
                    -- if it is a null set it to application/octect
                    -- application/octect may launch a download window from windows
                    owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE );
                -- set the size so the browser knows how much to download
                --htp.p('Content-length: ' || v_length);
                -- the filename will be used by the browser if the users does a save as
                --htp.p('Content-Disposition: attachment; filename="'||substr(v_file_name,instr(v_file_name,'/')+1)|| '"');
                -- close the headers
                owa_util.http_header_close;
                -- download the BLOB
                wpg_docload.download_file( Lob_loc );
end download_my_file;
/I have changed the table name back to the original one (I have also provided the needed grants) and I have commented out the 2 lines needed to show the open/save dialog.
When I now call this procedure my excel document is embedded in the browser.
