my heads hurt from trying to figure this out!
I have three tables -Players -Teams -Games
Three junction tables with two columns. -player_teams -teams_games -player_games
I need to list all Players who are in a Game (eg: Game_id = 111 from variable) that are not assigned a Team(in this game). i call them orphaned players
Basically get Teams that are in the game, get their Players and reverse match against Games_players. or the other way round i suppose.
i tried for two day no luck!
thanks!
/J p.s after i posted this i got this far but it seems to complex!
SELECT * from players
JOIN
(SELECT DISTINCT games_players.player_id from games_players
Left JOIN
(Select team_players.player_id p1 from team_players
inner join (Select * from games_teams where games_teams.game_id = :P1) AS tm1 ON team_players.team_id = tm1.team_id) As f1
On games_players.player_id = f1.p1
where p1 is null) as q1
on players.player_id = q1.player_id
As the game is given, you can just look at the players in the game and the players of the teams in the game:
select *
from players
where player_id in
(
select player_id
from player_games
where game_id = 111
)
and player_id not in
(
select pt.player_id
from player_teams pt
join teams_games tg using (team_id)
where tg.game_id = 111
);
