Select multiple sums with MySQL query and display them in separate columns

Question

Let\'s say I have a hypothetical table like so that records when some player in some game scores a point:

name   points
------------
bob     10
mike    03
mi         


        

Answer 1

Are the player names all known up front? If so, you can do:

SELECT SUM(CASE WHEN name = 'bob'  THEN points ELSE 0 END) AS bob,
       SUM(CASE WHEN name = 'mike' THEN points ELSE 0 END) AS mike,
       ... so on for each player ...
  FROM score_table

If you don't, you still might be able to use the same method, but you'd probably have to build the query dynamically. Basically, you'd SELECT DISTINCT name ..., then use that result set to build each of the CASE statements, then execute the result SQL.
