Möchten Abfrage Auswahl aus einer Tabelle basierend auf nicht in einer anderen Tabelle erscheinen

Question

Ich habe drei Tabellen: player(playerId, Name), game(gameId, gameName) und .

Ich möchte die Zeilen von gameResults, wo gameId nicht existiert in Tabelle game.

Meine Frage ist:

SELECT DISTINCT 
    gameresults.playerId, 
    gameresults.results  
FROM 
    game, 
    gameresults, 
    player 
WHERE 
    gameresults.playerId = player.playerId 
    AND gameresults.gameId NOT IN (
     SELECT game.gameId; FROM game 
    ) 

auch ich versucht:

SELECT DISTINCT 
    gameresults.playerId, 
    gameresults.results  
FROM 
    game, 
    gameresults, 
    player 
WHERE 
    gameresults.playerId = player.playerId 
    AND gameresults.gameId NOT EXISTS(
      SELECT race.raceId, FROM race 
    ) 

Answer 1

SELECT DISTINCT gameresults.playerId, gameresults.results, game.gameName 
FROM gameresults 
    LEFT JOIN game ON game.gameId = gameresults.gameId 
/* WHERE gameresults.gameName Is NULL <-- incorrect */ 
WHERE gameresults.gameId IS NULL; 

Answer 2

SELECT * FROM gameResults 
WHERE gameId NOT IN (SELECT gameid FROM game) 

schnell und schmutzig, aber seine leicht
