Mysql Query With Rank

Hey guys...

Yeah its me again

Another thing i need to figure out...

the DB structure is with id, user_id, score,

i have a user_id and a score (number)... and i want to count the entries from the DB... order by score and gives back the Rank/place/count if the user_id matches...

for example:

id=1 user_id=2 score=50 <--------- 1. place
id=2 user_id=3 score=23 <--------- 3. place
id=3 user_id=7 score=34 <--------- 2. place

i hope you can understand what i mean, and help me with that... thanks...

Re: Mysql Query With Rank

Code: [Download] [Hide]

SELECT user_id, username, user_rank, user_rank2, user_rank3 ... 
FROM USERS_TABLE 
ORDER BY score DESC 

The PHP code should'nt be too difficult ;-). Something like

Code: [Download] [Hide]

<?php $result = $db->sql_result($sql);

 $place = 0;

 while ($row = $db->sql_fetchrow($result))

 {

     echo 'Hi I\' ' . $row['username'] . ', id ' . $row['user_id']  . '. My place is ' . ++$place . ', and my first rank is ' . $row['user_rank'] . '<br />'; //feel free to display more ranks

 }

Re: Mysql Query With Rank

(use code syntax=php !)
For the group query, use something like

Code: [Download] [Hide]

AND g.group_id NOT IN (1, 2, 3, 4, 5, 43)

Much more readable than

Code: [Download] [Hide]

                    AND g.group_id <> 1 
                    AND g.group_id <> 2 
                    AND g.group_id <> 3 
                    AND g.group_id <> 4 
                    AND g.group_id <> 5 
                    AND g.group_id <> 43 

For everything else, it looks good. Nice job ;-).
