如何从表到另一个表获取记录？

Question

我有下表。我需要从我的寄存器表中获取有StudentID＆amp;的记录。类ID，到证书表。我不知道如何做到这一点，我对此有正确的查询或关系！

Tables:
Certificates(StudentID, ClassID, CertificateID, Mark)
Student(StudentID, FirstNameFA, LastNameFA)
Registers(RegisterID, StudentID, ClassID)
Classes(ClassID, LessonType)

Tables

我试过了：

SELECT Registers.StudentID
    ,Students.NationalityCode
    ,Registers.ClassID
    ,Students.FirstNameFA
    ,Students.LastNameFA
    ,Students.FirstNameEN
    ,Students.LastNameEN
    ,Certificates.Grade
    ,Certificates.Issued
    ,Certificates.CertificateID
    ,([FirstNameFA] + " " + [LastNameFA]) AS FullNameFA
    ,([Sex] + " " + [FirstNameEN] + " " + [LastNameEN]) AS FullNameEN
FROM Classes
INNER JOIN Students
LEFT JOIN Certificates ON Students.StudentID = Certificates.StudentID
INNER JOIN Registers ON Students.StudentID = Registers.StudentID 
         ON Classes.ClassID = Registers.ClassID 
WHERE Registers.ClassID IS NOT NULL
    AND Registers.ClassID = [Forms] ! [Class Report] ! [cbClass];

我仍然无法在我的证书表格中添加此查询中的任何记录。我需要在每个有班级的学生的证书表中加上标记。
