mysql - Finding a unique value from 2 columns and then a ratio of those values -


i have table columns id, player1, , player2. id's player can in either of 2 columns. need find unique id's in column player1 , column player2 combined. need find amount of times each player appears in each column. want order ratio of column player1 / column player2.

for instance, have following values in table.

1 103 101

2 103 111

3 232 103

4 223 111

my query return..

player 223: 1/0

player 232: 1/0

player 103: 2/1

player 101: 0/1

player 111: 0/2

i know unique ids can this

select  (select group_concat(distinct player1) table) player1, (select group_concat(distinct player2) table) player2

and know order can this

order player1 / player2 desc

i'm having hard time figuring out once unique id , try ratios outputed , sorted

try this

select player1,player2, concat('player',if( (select count(dt.player1) table dt mt.player1 = dt.player1) > 0, player1,player2),':', (select count(dt.player1) table dt mt.player1 = dt.player1), ' / ', (select count(dt.player2) table dt mt.player2 = dt.player2) )   table mt player1 != player2 group palyer1,player2 order (player1/if(player2 not null , player2 != 0,player2,1) desc

i hope helps you
