Reader Johann Preissl writes in with a pure T-SQL solution to the Five-House Logic Puzzle. No tables or VBA required!

In part 2 of my Access solution for the five-house logic problem, we test the neighborhood class module.

In part 1 of my Access solution for the five-house logic problem, I demonstrate the class module I used to model a neighborhood configuration.

In this follow-up to my post on the classic Five-House Logic Problem, I provide the solution to the riddle plus a few tips for finding it.

In part 1 of this series, I introduce a classic logic problem that took me nearly two hours to solve by hand. Later in the series, we'll use Access to program a solution.
