Say I have two tables:
Sales:
Manufacturer Model Number sold
========= ===== ========
Ford F10 16
Ford Model T 13
Chevy Nova 2
VW Golf 3
VW Beetle 712
Stock:
Manufacturer Model Number In Stock
========= ===== ===========
Ford Fairmont 31
Porsche 911 99
Renault Le Car 1
Cadillac El Dorado 2
VW Square Back 71
I would like to combine this data with a query for results like:
Manufacturer Number Sold Number in Stock Total
========= ========= =========== ====
Ford 29 31
60
Chevy 2 0
2
etc...
This isn't the real data, of course, just a similar example. I am just a
little fuzzy on how to get this together on SQL. Anyone have any pointers?
Muchas Gracias.

I was thinking of an ethanol overdose, but you may have a point.

You want to look for "outer join" and "group by". Group each of the two
tables my manufacturer to SUM() up the number sold and number in stock, then
do an outer join on the manufacturer name (replacing NULL with 0 before
display).

Not really, no - and the HTML portion of the message is generally not a
lot of use. ;-)
