MySQL从多个总和中选择最大值

Question

I am using the following results table

Results Table
__________________________________________
player_a| player_b | player_c |   year 
________|________  |__________|___________|
100      150        150        2015  
100      -50        -50        2015 
100      350        250        2014
200      350        250        2014  

What i would like to do is get the sum for each player per year. Using the following Select i get the desired results.

SELECT (

SELECT SUM( player_a )
FROM `results`
WHERE year =2015
) AS player_a_2015, (

SELECT SUM( player_a)
FROM `results`
WHERE year =2014
) AS player_a_2014

How can i get the maximum sum result only ?

ie For player_a should be 300

Answer 1

SELECT SUM(player_a) AS spa
FROM results
GROUP BY year
ORDER BY spa DESC
LIMIT 1

Answer 2

This should do it.

Make sure you wrap your OR condition in parenthesis so it evaluates them both.

SELECT SUM(player_a) AS sum_score
  FROM results
 WHERE (year = '2015' OR year = '2014')

EDIT

If you're wanting the maximum score by year, and then to sum that - this should be OK.

SELECT MAX(max_sum_score) AS max_sum_score
  FROM ( SELECT year
              , SUM(player_a) AS max_sum_score
           FROM results
          WHERE (year = '2015' OR year = '2014')
          GROUP BY year 
       ) a

Answer 3

You may wanna use,

SELECT MAX(SUM_A),YEAR FROM (
    SELECT SUM( player_a ) as SUM_A, YEAR
    FROM results
GROUP BY YEAR
) A_SCORE;

This will do it in one go(obviously for one player).
