There is one caveat here: unless you are 100% certain that the
product.pieces count is 100% accurate, you should sum the
orderitems.productid.  It is pretty common for the indirect counts (like
product.pieces) to get out of sync with the "normal" source of truth (line
items).  

This does depend on design of your system, of course.
