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

In pure sql:

SELECT
    sum( (name = 'bob') * points) as Bob,
    sum( (name = 'mike') * points) as Mike,
    -- etc
FROM score_table;

This neat solution works because of mysql's booleans evaluating as 1 for true and 0 for false, allowing you to multiply truth of a test with a numeric column. I've used it lots of times for "pivots" and I like the brevity.
