Question

My Database structure

Table 'Player'   : column 'id'
Table 'Score'    : column 'player_id' , 'score' , 'time'

example data in Table ‘Score’

   player_id       score             time
     1001           100      2000-01-01 00:00:00
     1001             3      2012-08-01 00:00:00
     1001            11      2012-08-02 00:00:00
     1002            80      2012-07-01 00:00:00
     1002             5      2012-08-01 00:00:00
     1003            90      2012-07-01 00:00:00

I try to use

SELECT * FROM Score WHERE MONTH(time) = MONTH(NOW()) ORDER BY score DESC

The result from Player 1001 will be multiple row of score 11 and 3.
How to sort and get only max score in time length that should be only score 11 of Player 1001

The result should be

   player_id       score             time
     1001            11      2012-08-02 00:00:00
     1002             5      2012-08-01 00:00:00

not

   player_id       score             time
     1001            11      2012-08-02 00:00:00
     1001             3      2012-08-01 00:00:00
     1002             5      2012-08-01 00:00:00

Answer 1

SELECT player_id, max(score) as max_score
FROM Score 
WHERE MONTH(time) = MONTH(NOW()) 
group by player_id
ORDER BY max_score DESC
