有您已經閱讀說明書？ http://dev.mysql.com/doc/refman/5.1/en/join.html這是一個常見的情況。 – Lekensteyn 2011-03-05 09:54:26

你說你想獲得實際學生的數據，但是你甚至沒有在你的問題中包含該表。 – 2011-03-05 10:00:33

要加入多個表的方式，你可以使用同樣的技術加入2個表：

SELECT * 
FROM registration 
JOIN registrationschedule ON registration.regschedid = regschedid 
JOIN student ON registration.studentid = student.studentid 
--- etc

SELECT registration.*,registrationschedule.*, session.*,schedules.*,faculty.* 
FROM registration 
LEFT JOIN registrationschedule on registration.regschedid = registrationschedule.regschedid 
LEFT JOIN session on session.regschedid = registrationschedule.regschedid 
LEFT JOIN schedules on schedules.regschedid = session.regschedid 
LEFT JOIN faculty on faculty.teacherid = schedules.teacherid 
WHERE registrationid = 1;
