I can do nearly everything with Paradox ObjctPal code, but have a simple question about defining a query in paradox itself:
Table "orders" with fields "customer" and "product",
and table "customers" with field "customer". Each customer has baught several products, some are different, same the same.
I have joined the tables.
I need this information:
How many customers have ordered a certain product?
Result for this small example:
3 customers have bought product A.
How to define a query for some thousands of customers / orders?
