sql - Access 2010：加入三个表，未知错误

Question

我正在尝试在 SQL 查询中加入 MS Access 2010 中的三个表。

SELECT Track.trackName, TrackIsGenre.genre, ContainsTracks.albums
FROM Track 
INNER JOIN TrackIsGenre ON  Track.trackName = TrackIsGenre.track
INNER JOIN ConstainsTracks ON Track.trackName = ContainsTracks.tracks
WHERE genre = "Rock"
ORDER BY trackName ASC;

我搜索了网络，据我所知，应该是这样。我可以加入两个表没问题。我得到的错误是：“查询表达式中的语法错误（缺少运算符）”，它突出显示了两个 INNER JOIN。

任何帮助将不胜感激。

在您第一次加入时添加一个括号，（这在 MOST RDBMS 上是可选的）

SELECT  Track.trackName, TrackIsGenre.genre, ContainsTracks.albums
FROM    (Track INNER JOIN TrackIsGenre ON  Track.trackName = TrackIsGenre.track)
        INNER JOIN ConstainsTracks ON Track.trackName = ContainsTracks.tracks
WHERE   genre = "Rock"
ORDER   BY trackName ASC;
