SQL多次選擇一列

Question

所以我有兩個表：

create table teams(
teamShortName varchar(3) not null,
teamLongName varchar(35) not null,
PRIMARY KEY(teamShortName)
)

create table results(
matchID int identity(1,1)
homeTeam varchar(3) not null references teams(teamShortName),
awayTeam varchar(3) not null references teams(teamShortName),
homeTeamGoals int not null,
awayTeamGoals int not null,
PRIMARY KEY(matchID)
)

現在，我想創建可以給我結果但帶有teamLongNames的視圖/選擇...

嘗試了一些東西，但沒有成功-主隊和客隊獲得相同的名稱/雙方均為空值

數據看起來像這樣

teamShortName     teamLongName
     RMD         FC Real Madrid
     FCB         FC Barcelona

matchID     homeTeam   awayTeam   homeTeamGoals   awayTeamGoals
   1           RMD        FCB           2               2

結果看起來像這樣

    Home        HomeGoals        AwayGoals        Away
FC Real Madrid      2                2         FC Barcelona

感謝您的幫助：）

使用別名，您可以鏈接表兩次

SELECT HT.teamLongName, homeTeamGoals, aT.teamLongName, awayTeamGoals
FROM results INNER JOIN teams HT on  homeTeam = HT.teamShortName
INNER JOIN teams AT ON awayTeam = AT.teamShortName
