Stumbled across these links on my Digg RSS feed. Two articles showing how to solve Sudoku puzzles with T-SQL and with Oracle SQL. I’ve been writing database doc long enough to find that absolutely awesome. Each article shows a few useful and complex SQL techniques. The T-SQL article is particularly well-written, even if it doesn’t share all the stored procedures used to solve the puzzle.
While many like the pencil-and-paper method of play, there is WebSudoku with an Option that lets you write more than one number in the square as if you were penciling in possibilities. Plus, it times your solving abilities and lets you measure up against all other players in the past week who solved that puzzle. My half-hour-long first completion of an easy puzzle didn’t do well against the six minute mark set by many of the previous week’s players.
