Answer 1

使用不同的别名（T1和T2）加入elem.myProperty两次：

tblTeam

示例结果：

SELECT ScheduleID,DateTime,T1.Name as [Team-1],T2.Name as [Team-2]
FROM tblSchedule S JOIN
     tblTeam T1 ON S.Team_1=T1.TeamID JOIN 
     tblTeam T2 ON S.Team_2=T2.TeamID
ORDER BY S.ScheduleID

SQL Fiddle

中的示例结果

Answer 2

我喜欢使用子查询来解决这类问题，以避免额外加入 产品

SELECT 
    CONVERT(varchar(20), DateTime, 100) AS DateTime, 
    (SELECT Name FROM tblTeam WHERE s.Team_1 = TeamID) AS Team-1, 
    (SELECT Name FROM tblTeam WHERE s.Team_2 = TeamID) AS Team-2 
FROM tblSchedule s
