in reply to Re^2: reordering a stack with little effort
in thread reordering a stack with little effort

this is actually a very nice idea... you would simply ORDER BY NEXT instead of ORDER BY QUESTION_NUM. To tell the truth, I thought of using this method, but chose to implement the decimal system instead. I still think this is better, but since my decimal system is already working, I am gonna leave it in place. For my next implementation, I am going to use a linked list.

    Sadly, no -- once you start rearranging the questions, the values in the "next" column need not be in ascending numerical order... I think you'll need to sort them in Perl rather than at the SQL DBMS.
