請分享你的表結構 –

我想對於這一點，你必須做一些PHP代碼來設置所需的表 – Priyank

學生{Studentid ，StudentName，...} subject {Subjectid，SubjectName，...} marks {studentid，Subjectid，mark，...} 與上述結構相同。 – Vaishali

假設你的表結構如下：

student {Studentid, StudentName, ...} 
subject {Subjectid, SubjectName, ...} 
marks {Studentid, Subjectid, mark , ...} 

select Studentid, StudentName, a.mark Sub1, b.mark Sub2, c.mark Sub3, d.mark Sub4, e.mark Sub5, f.mark Sub6, 100 Outof 
from student, marks a, marks b, marks c, marks d, marks e, marks f 
where student.Studentid = a.Studentid and a.Subjectid = 901 
and student.Studentid = b.Studentid and b.Subjectid = 902 
and student.Studentid = c.Studentid and c.Subjectid = 903 
and student.Studentid = d.Studentid and d.Subjectid = 904 
and student.Studentid = e.Studentid and e.Subjectid = 905 
and student.Studentid = f.Studentid and f.Subjectid = 906

然而更好的使用PHP來產生結果。當有空數據，以避免左聯接

"SELECT s.student_register_id, 
     s.student_first_name, 
     a.mark Sub1, 
     b.mark Sub2,  
     c.mark Sub3, 
     d.mark Sub4, 
     e.mark Sub5, 
     f.mark Sub6, 
     100 Outof 
FROM student_register s, marks a, marks b, marks c, marks d, marks e, marks f 
INNER JOIN class_teacher k ON k.division_id=s.division_id 
WHERE (s.student_register_id = a.student_register_id AND a.Subjectid = 100) 
AND (s.student_register_id = b.student_register_id AND b.Subjectid = 102) 
AND (s.student_register_id = c.student_register_id AND c.Subjectid = 103) 
AND (s.student_register_id = d.student_register_id AND d.Subjectid = 104) 
AND (s.student_register_id = e.student_register_id AND e.Subjectid = 105) 
AND (s.student_register_id = f.student_register_id AND f.Subjectid = 106) 
AND k.class_teacher_id='".$_SESSION['class_teacher_id']."'";

你可以試試這個
