Solving a Sudoku with Oracle
Being a database developer, I’ve seen some fairly interesting things you can do with Oracle 11g.
This beats everything I know thus far.
Oracle RDBMS 11gR2 introduced a new feature called Recursive Subquery Factoring. Besides being an alternative to hierarchical queries (classic “connect by” stuff), you can use it to solve a Sudoku…in 29 lines of SQL code.
Mind = Blown
Thanks for the link, Alex!
