Count files downloaded or viewed

Question

I am currently using the File Upload and Download Application described in How-to Documents. I open a new browser window with my pdf document with javascript. I would like to keep track how many times a file is viewed. I added a simple query in the download procedure that inserts the ID and sysdate into a table. This seems to work but I get a double post to the table. Is there a way to keep this from posting twice.

Answer 1

The query is in the document_download procedure:
PROCEDURE download_document(p_file IN NUMBER,p_type IN VARCHAR2) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
SELECT MIME_TYPE, BLOB_CONTENT, file_name,DBMS_LOB.GETLENGTH(blob_content)
INTO v_mime,lob_loc,v_file_name,v_length
FROM rlappntl.PRICE_RATE_SHEETS
WHERE rs_nbr = p_file;
owa_util.mime_header( NVL(v_mime,'application/pdf'),FALSE );
htp.p('Content-length: ' || v_length);
owa_util.http_header_close;
wpg_docload.download_file( Lob_loc );
INSERT INTO RLAPPNTL.PRICE_USAGE_COUNTER (APPLICATION, DATE_USED)
VALUES (p_type, SYSDATE);
END download_document;
