Question

I’ve created a game with a highscore table in MySQL.

I have a “My scores” button that needs to retrieve the users scores, e.g.:

10. John  395

42. John  340

90. John  10

How should I go out retrieving the rank (10th, 42th, 90th) of each score of the user?
I could pull all the scores from the database and iterate through them but that doesn’t seem like a good solution.

Let me try to expand:
I retrieve all MY scores from the database. E.g. 10 scores. I want to display these 10 scores however I won’t know what the rank of these scores is compared to the other scores in my database! (10th, 16th, etc) ..Hope that makes more sense…

Thanks

For the position in the total list you either need to build up a list every time you want this overview, or use a stored procedure to build a list for a given moment. You could ‘cache’ a list on a given interval. Or maybe update a list when some one played a game that would change the top 100.

As @WhiteElephant suggested, you’d be making the table every time you want the data.
@stefandoorn suggest to not use the optimized count of sql, i think this is not efficient enough for these kind of computations.
