Sudoku Recursive Common Table Expression Solver

Colin, from Percona, wrote a nice post demonstrating a funny use of common table expressions: solving a Sudoku Puzzle. Ok, that's not the type of problem which matters a lot to database users... but it still feels good when he mentions that MySQL's implementation (which I wrote), is the fastest of all three tested DBMSs 😊.

  1. Dans le mĂȘme ordre d'idĂ©e, j'ai autrefois Ă©crit un article en 3 parties sur comment rĂ©soudre des sudokus en SQL. L'article est assez long, dĂ©taillĂ© et, surtout, en français pour ceux que ça intĂ©resse!!

    Partie 1 (https://endormitoire.wordpress.com/2012/01/07/comment-presser-un-citron-premiere-partie/),
    Partie 2 (https://endormitoire.wordpress.com/2012/01/08/comment-presser-un-citron-deuxieme-partie/)
    Partie 3 (https://endormitoire.wordpress.com/2013/05/27/comment-presser-un-citron-troisieme-partie/).

    Comment presser un citron? Vous le saurez en lisant l'article!
