Question

I have the following table:

  userid  compid round score    bonus
  2980    3     0     50          0
  50        3     0     80          0
  52        3     0     80          0
  55        3     0     20          0
  58        3     0     100         0
  106      3     0     120         0
  555      3     0     50          0
  100     3     0     30          0
  50        3     1     90          0
  52        3     1     50          0
  106      3     1     30          0

I want to be able to not only sum the score and bonus cols per user for all rounds, but rank them accordingly. It should be able to handle ties with the sequence 1,2,2,4,5,5,5,8:

Trick is I don’t want to create a temp table or insert the ranking into the table. Also, i can not limit the return – so it need to rank the entire table regardless of rounds completed.

I have managed to rank the rows but can’t seem to group them with the sum. And of course I have managed the sum separately – I just need to ‘join’ the two steps.

Obtaining sums per user:

SELECT userid,sum(score+bonus) as tscore from entries 
group by userid order by tscore desc

userid  tscore
50      170
106    150
52      130
58      100
2980      50
555    50
100    30
55        20

rank without the score sum : (thanks MySQL Cookbook)

SELECT @rownum := @rownum + 1 AS row,
@rank := IF(@prev_val!=score,@rownum,@rank) AS rank,
userid,
@prev_val := score AS score
FROM exodus_entries ORDER BY score DESC

row   rank  userid      score
1      1    106         120
2      2    58          100
3      3    50          90
4      4    50          80
5      4    52          80
6      6    52          50
7      6    555         50
8      6    2980        50
9      9    100         30
10    9     106         30
11    11    55          20

Thanks for the time and help! All advice welcome!

SELECT @rownum := @rownum + 1 AS row,
    @rank := IF(@prev_val!=score,@rownum,@rank) AS rank,
    userid,
    @prev_val := score AS score
FROM (
    SELECT userid, sum(score+bonus) as score 
    from entries 
    group by userid 
) exodus_entries 
ORDER BY score DESC
