so basically, require query return display name, amount of kills , amount of deaths. i have 2 tables need pull from. the 2 tables are player id | name 2334324 | user 4353454 | user2 where id unique identifier , name display name. the second table is: player_kill id | killer | victim | 1 | 2334324 | 4353454 | 2 | 2334324 | 4353454 | 3 | 4353454 | 2334324 | where killer / victim columns contain unique identifier of player table. i'd able count occurrences of player id in killer , victim query returns: name | kills | deaths user | 2 | 1 user2| 1 | 2 where number under kills amount of occurrences playerid has in killer column , same deaths hope provided enough information. what have far: select `player`.`name`, count(distinct `player_kill`.`id`) `kills`, count(distinct `player_kill`.`id`) `deaths` `player` left join `player_kill` on `player`.`id`=`player_kill`.`killer` left join `player_kill` on `player`.`id`=`player_kill`.
