Hej alla,
First of all, a Happy New Year for all of you! My vacations are gone and I now have to
come back to my true reality... Databases and PHP. :)
A very interesting question for you experts. Let's see if you can help me.
I am developing a game with a team and I have to store the scores of users on a MySQL
database to create a ranking. I have a MySQL table called ranking and this table has
got the following fields:
user VARCHAR(12) NOT NULL /* nickname of the user */
mpontos INT NOT NULL /* amount of points per month */
Very simple, huh? Here comes the tricky part... I want to search for a specific user
and make a query that is able to identify the user one position ahead and the user one
position behind. Something like this:
user mpontos
UserA 1532
James Brown 1349
UserB 1229
The most important part is that it cannot be any user with more or less points than
James Brown. It must be exactly the users with the smallest difference to his amount
of points. Do you have any suggestions?
The second part of my problem includes the first one and tries to go in a little bit
further... Using the example above, is it possible to "ask" MySQL for the actual
position of James Brown and the other users on that specific table according to the
amount of points? Something like this:
user mpontos position
UserA 1532 12
James Brown 1349 13
UserB 1229 14
Any suggestions you experts?
Thanks in advance!!!
