Subject Re: AW: AW: foreign-key generation maps NumberKey to int, and code fails to compile
Date Tue, 14 Aug 2007 08:14:09 GMT

Each coupon is owned by one member.
A member may have any number of coupons.
SQL has no trouble setting up such a relationship without a third table.  Do
I need the third table to satisfy Torque?
