Question

我想加入两张桌子，两次：

Fixtures表（Fixture ID，HomeTeamID，AwayTeamID）
Team表（TeamID，TeamName）

使用以下查询：

CREATE VIEW [dbo].[Test1]
AS 
    SELECT 
        XMLFixture.ID AS ID, 
        HomeTeam.Name AS HomeTeam, AwayTeam.Name as AwayTeam
    FROM 
        [XMLSoccer-Fixture] XMLFixture
    INNER JOIN 
        [XMLSoccer-Team] HomeTeam ON HomeTeam.ID = XMLFixture.HomeTeamID
    INNER JOIN 
        [XMLSoccer-Team] AwayTeam ON AwayTeam.ID = XMLFixture.AwayTeamID

我遇到的问题是，对于每个HomeTeam，它还会返回整个远离球队列表。所以，如果我有1000个团队。每个团队都会为HomeTeam返回1,000条记录。我想我需要以某种方式调整我的加入，但不太确定如何，

提前致谢

Answer 1

似乎我的TeamID方向错误，这很好用：

CREATE VIEW [dbo].[Test1]
AS 
SELECT 
    XMLFixture.ID AS ID, 
    HomeTeam.Name AS HomeTeam, AwayTeam.Name as AwayTeam
FROM 
    [XMLSoccer-Fixture] XMLFixture
INNER JOIN 
    [XMLSoccer-Team] HomeTeam ON XMLFixture.HomeTeamID = HomeTeam.ID
INNER JOIN 
    [XMLSoccer-Team] AwayTeam ON XMLFixture.AwayTeamID = AwayTeam.ID

SQL Inner Join两个表，提供两组数据
