primary key isn'trelevant, however, the product_number is (it
isunique). iiuc, in my case i should use
product_numberinstead of primarykey.it makes sense - thanks
for the enlightenment.
(slightly off topic) You might consider changing
your table structure so product_number is your primary key, if it always
unique. That way you don't need an additional primary key field. Just a
suggestion.
