If you recall, I like Sudoku.  I even posted a script for solving it via TSQL.  I went so far as to enter my script into a TSQL Challenge.  That all started way back in August.  Today, I have an update!!

I was notified this morning from BeyondRelational.com that I have earned a new badge.  Cool, what’s the badge?  I clicked the link and it took me to this badge.
Huh?  I’m a winner of the SQL Sudoku Challenge?  Awesome!

Looking it over, I am winner #3.  This means I could have done better with my solution.   And looking at the other solution stats, it appears I will need to find time to see what the others did to make their solutions go sooooo fast.  I have some learning to do – woohoo.

So, now that means I need to post my solution.

[codesyntax lang="tsql"]



Sadly, that is not the most recent version of the script that I had.  I had intended on submitting this version, which is still slightly faster.

[codesyntax lang="tsql"]


Still, I am certain that (without having looked at the other winning solutions) this is not on par with the best solutions.  And I have a lot to learn.
