关于一个简单的SQL语句的有关问题

求助：关于一个简单的SQL语句的问题
我需要往gridview里绑定数据，现在语句如下：
SELECT Elect.stuID, Student.stuName, Elect.Score FROM Elect INNER JOIN Student ON Elect.stuID = Student.stuID WHERE (Elect.courceID = @courceID)

现在我需要在把Homework表里的uploadFile 也绑定进去 homework表里有stuID，homework，uploadFile，其中要求
Elect.stuID = Student.stuID=homework.stuID

------解决方案--------------------

SQL code

SELECT Elect.stuID, Student.stuName, Elect.Score, Homework.uploadFileFROM Elect INNER JOIN Student ON Elect.stuID = Student.stuID INNER JOIN Homework ON Elect.stuID = homework.stuIDWHERE (Elect.courceID = @courceID)
