Question

我正在尝试创建一个查询，该查询将根据另外两个查询的并集输出前6个结果。这两个查询如下：

SELECT GameData.GameID,
    GameData.DivisionID,
    GameData.SeasonID,
    GameData.HomeTeamID AS TeamID,
    GameData.GameDate,
    IIf([FullTimeResult] = 'H', 1, 0) AS W,
    IIf([FullTimeResult] = 'D', 1, 0) AS D,
    IIf([FullTimeResult] = 'A', 1, 0) AS L,
    IIf([HalfTimeResult] = 'H', 1, 0) AS WHT,
    IIf([HalfTimeResult] = 'D', 1, 0) AS DHT,
    IIf([HalfTimeResult] = 'A', 1, 0) AS LHT,
    GameData.FullTimeHomeGoals AS GS,
    GameData.FullTimeAwayGoals AS GC,
    IIf([FullTimeResult] = 'H', 3, IIf([FullTimeResult] = 'D', 1, 0)) AS P,
    GameData.HalfTimeHomeGoals AS GSHT,
    GameData.HalfTimeAwayGoals AS GCHT,
    GameData.HomeShots AS Sh,
    GameData.AwayShots AS ShA,
    GameData.HomeShotsOnTarget AS ShOnT,
    GameData.AwayShotsOnTarget AS ShAOnT,
    GameData.HomeFouls AS FM,
    GameData.AwayFouls AS FA,
    GameData.HomeCorners AS C,
    GameData.AwayCorners AS CA,
    GameData.HomeYellowCards AS YC,
    GameData.AwayYellowCards AS YCA,
    GameData.HomeRedCards AS RC,
    GameData.AwayRedCards AS RCA
FROM TeamsDivSea
INNER JOIN GameData ON TeamsDivSea.TeamID = GameData.HomeTeamID
WHERE (
        (
            (GameData.GameID) IN (
                SELECT TOP 3 GameID
                FROM GameData AS Dupe
                WHERE Dupe.HomeTeamID = GameData.HomeTeamID
                ORDER BY Dupe.GameDate DESC,
                    Dupe.GameID DESC
                )
            )
        );

SELECT GameData.GameID,
    GameData.DivisionID,
    GameData.SeasonID,
    GameData.AwayTeamID AS TeamID,
    GameData.GameDate,
    IIf([FullTimeResult] = 'A', 1, 0) AS W,
    IIf([FullTimeResult] = 'D', 1, 0) AS D,
    IIf([FullTimeResult] = 'H', 1, 0) AS L,
    IIf([HalfTimeResult] = 'A', 1, 0) AS WHT,
    IIf([HalfTimeResult] = 'D', 1, 0) AS DHT,
    IIf([HalfTimeResult] = 'H', 1, 0) AS LHT,
    GameData.FullTimeAwayGoals AS GS,
    GameData.FullTimeHomeGoals AS GC,
    IIf([FullTimeResult] = 'A', 3, IIf([FullTimeResult] = 'D', 1, 0)) AS P,
    GameData.HalfTimeAwayGoals AS GSHT,
    GameData.HalfTimeHomeGoals AS GCHT,
    GameData.AwayShots AS Sh,
    GameData.HomeShots AS ShA,
    GameData.AwayShotsOnTarget AS ShOnT,
    GameData.HomeShotsOnTarget AS ShAOnT,
    GameData.AwayFouls AS FM,
    GameData.HomeFouls AS FA,
    GameData.AwayCorners AS C,
    GameData.HomeCorners AS CA,
    GameData.AwayYellowCards AS YC,
    GameData.HomeYellowCards AS YCA,
    GameData.AwayRedCards AS RC,
    GameData.HomeRedCards AS RCA
FROM TeamsDivSea
INNER JOIN GameData ON TeamsDivSea.TeamID = GameData.AwayTeamID
WHERE (
        (
            (GameData.GameID) IN (
                SELECT TOP 3 GameID
                FROM GameData AS Dupe
                WHERE Dupe.AwayTeamID = GameData.AwayTeamID
                ORDER BY Dupe.GameDate DESC,
                    Dupe.GameID DESC
                )
            )
        );

是否可以仅使用一个SELECT TOP语句创建联合查询，因此只有前6个从联接结果中输出？

非常感谢

这应该有效 - 基本上UNION您的两个查询并选择前6个。

SELECT TOP 6 GameID, DivisionID, SeasonID, TeamID, GameDate, W,D,L,WHT,DHT,LHT,GS,GC,P,GSHT,GCHT,Sh,shA, shOnT, ShAOnt, FM,FA,C,CA,YC,YCA,RC,RCA

    SELECT GameData.GameID,
        GameData.DivisionID,

        GameData.HomeTeamID AS TeamID,
        GameData.GameDate,
        IIf([FullTimeResult] = 'H', 1, 0) AS W,
        IIf([FullTimeResult] = 'D', 1, 0) AS D,
        IIf([FullTimeResult] = 'A', 1, 0) AS L,
        IIf([HalfTimeResult] = 'H', 1, 0) AS WHT,
