There comes a time when the monotony of work needs a little refreshing diversion. Some of us like to relax (or frustrate) the time a way with a Sudoku puzzle which is fast becoming pandemic craze.
I enjoy solving these puzzles myself, but with a lust for a challenge, I could not resist the opportunity to develop a Sudoku puzzle solver written entirely in Oracle SQL and PL/SQL.
By developing this solver I have also demonstrated how it is possible to develop a relatively simple solution to solve a reasonably difficult problem.
Others have now joined in to help enhance the usability of the solver, with special thanks to Patrick Barel who has developed a very simple but effective Windows front-end in Delphi using Qnxo, which is now included in the download.
