mysql选择内连接给我循环结果

Question

嗨大家好我难以接受以下mysql查询的问题：

SELECT 
tp.ID AS tpid, 
p.firstName AS pfname, 
p.lastName AS plname, 
p.dob AS pdob, 
fix.homeTeamID AS fixhtid

FROM fixtures AS fix

INNER JOIN teamSeason AS ts ON fix.homeTeamID = ts.ID
INNER JOIN teamPlayers AS tp ON tp.teamSeasonID = ts.ID
INNER JOIN person AS p ON tp.personID = p.ID

WHERE fix.homeTeamID =2

我期望这个查询产生9行，但是有超过180行，原来的9行重复了19次。

我不知道如何解决这个问题，并且想知道是否有人可以帮助我 - 我的大脑很难。

我试图从查询中删除“fix.homeTeamID AS fixhtid”，但它不会停止循环结果。

有没有办法只显示结果而不循环？

我应该在线发布相关的mysql表，以便你看到吗？

谢谢

皮特

更新

我已将我的sql查询更新为：

SELECT 
tp.ID AS tpid, 

p.firstName AS pfname, 
p.lastName AS plname, 
p.dob AS pdob,

fix.homeTeamID AS fixhtid


FROM fixtures AS fix

INNER JOIN teamSeason AS ts 
ON ts.ID=fix.homeTeamID

INNER JOIN teamPlayers AS tp 
ON tp.teamSeasonID = ts.ID

INNER JOIN person AS p 
ON p.ID = tp.personID

WHERE fix.homeTeamID =2

GROUP BY tpid

正如Deepu所建议的那样。我添加了“GROUP BY”，它修复了我的结果。非常感谢Deepu和其他花时间回应的人。

第二次更新

我已将查询再次更新为：

SELECT DISTINCT tp.ID AS tpid,
    p.firstName AS pfname,
    p.lastName AS plname,
    p.dob AS pdob,

    fix.homeTeamID AS fixhtid

    FROM fixtures AS fix

    INNER JOIN teamSeason AS ts
    ON fix.homeTeamID=ts.ID

    INNER JOIN teamPlayers AS tp
    ON tp.teamSeasonID=ts.ID

    INNER JOIN person AS p
    ON tp.personID=p.ID

    WHERE fix.homeTeamID=2

草莓和约翰以最佳实践的名义建议我取代“GROUP BY”代替“SELECT DISTINCT”

谢谢大家。我学到了一些新东西。

您希望JOINS根据灯具的原始数据添加数据。然后你应该使用LEFT JOIN
