Mysql、内连接和子查询

Question

您好，我需要帮助这个问题:

计算并显示每个代表的编号和姓名以及他们获得的学分与类(class)代码、姓名和学分。

delegate    (StudentNumber,StudentName,Phone)
session     (Code,Date,Room)
take        (StudentNumber, CourseCode, Grade)
course      (CourseCode, CourseName,CourseCredits,)
module      (ModuleCode, ModuleName, Price,Credits,Course_Code(FK))

这是我到目前为止所拥有的:

SELECT no,name FROM delegate

INNER JOIN module,take
ON module.code = take.code

INNER JOIN course
ON CourseCredits = Credits

这就是我到目前为止所拥有的一切，任何帮助将不胜感激，我知道我必须使用子查询，但不太确定在哪里

Answer 1

SELECT no,name FROM delegate

INNER JOIN take ON take.StudentNumber = delegate.StudentNumber
INNER JOIN module ON module.code = take.code

INNER JOIN course ON CourseCredits = Credits

有帮助吗？
