Two ways to go about it. Enter a record into downloads when you enter
the product into products.
<CFQUERY DATASOURCE="mydatasource">
INSERT INTO products
(product_id,column2,column3,etc)
VALUES
(#product_id#,#column2#,#column3#,#etc#)
</CFQUERY>
<CFQUERY DATASOURCE="mydatasource">
INSERT INTO downloads
(product_id,downloadcount)
VALUES
(#product_id#,0)
</CFQUERY>
Then when they download:
<CFQUERY DATASOURCE="mydatasource">
UPDATE downloads
SET downloadcount = downloadcount + 1
WHERE product_id = #product_id#
</CFQUERY>
Or let them do it on the fly.
<CFQUERY DATASOURCE="mydatasource" NAME="indownloads">
SELECT product_id
FROM downloads
WHERE product_id = #product_id#
</CFQUERY>
<CFIF downloads.recordcount IS "0">
<CFQUERY DATASOURCE="mydatasource">
INSERT INTO downloads
(product_id,downloadcount)
VALUES
(#product_id#,1)
</CFQUERY>
<CFELSE>
<CFQUERY DATASOURCE="mydatasource">
UPDATE downloads
SET downloadcount = downloadcount + 1
WHERE product_id = #product_id#
</CFQUERY>
</CFIF>
