您试图执行不包含指定表达式的查询＆＃39;匹配号码＆＃39;作为聚合的一部分

Question

我正在尝试运行此功能，但上面的错误消息仍在继续。我已经尝试了一切，但似乎没有用。请任何人帮忙!!!

SELECT tblGameResults.MatchNumber,
       Sum(tblPlayerStatistics.Fouls_Made) AS Fouls
FROM tblGameResults 
INNER JOIN tblPlayerStatistics ON tblGameResults.MatchNumber = tblPlayerStatistics.MatchNumber
WHERE (((tblGameResults.Date_Of_Game)=[Date_Of_Game]) 
  AND ((tblGameResults.Place_Of_Game)=[Place_Of_Game]));

Answer 1

您需要GROUP BY对聚合值进行分组：

SELECT 
  tblGameResults.MatchNumber,
  Sum(tblPlayerStatistics.Fouls_Made) AS Fouls
FROM 
  tblGameResults 
INNER JOIN 
  tblPlayerStatistics ON tblGameResults.MatchNumber = tblPlayerStatistics.MatchNumber
WHERE (((tblGameResults.Date_Of_Game)=[Date_Of_Game]) 
  AND ((tblGameResults.Place_Of_Game)=[Place_Of_Game]))
GROUP BY 
  tblGameResults.MatchNumber;
