subjectId int           StubjectId int foreignkey from Subjects
Subject Name            StudentID int  foreignkey from Student
                        Marks int

Answer 1

当您发布SQL问题时，请包含架构和测试数据的脚本

您的初始SQL将类似于

select name, subjectname, marks
    from test t
    inner join student s on t.studentid = s.studentid
    inner join subject su on t.subjectid = su.subjectid 

和then you will need to pivot it 2 times
