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

you can use pivot function also for the same thing .. even by performance vise it is better option to use pivot for pivoting... (i am talking about oracle database)..

you can use following query for this as well.. -- (if you have only these two column in you table then it will be good to see output else for other additional column you will get null values)

select * from  game_scores
pivot (sum(points) for name in ('BOB' BOB, 'mike' MIKE));

in this query you will get data very fast and you have to add or remove player name only one place

:)

if you have more then these two column in your table then you can use following query

 WITH pivot_data AS (
            SELECT points,name 
  FROM   game_scores
  )
  SELECT *
  FROM   pivot_data
pivot (sum(points) for name in ('BOB' BOB, 'mike' MIKE));
