     SubjectName, SubjectDescription, SubjectShortCode 
from dbo.BS_Subject 
where BS_Subject.SubjectID <> (
SELECT  Distinct(BS_Subject.SubjectID) 
FROM   dbo.BS_Subject, dbo.BS_SubjectToClass 
Where  BS_Subject.SubjectID = BS_SubjectToClass.SubjectID

Sen NOT IN operatörünü kullanmak gerekir

Answer 1

SELECT SubjectID, DepartmentID, SubjectName, SubjectDescription, SubjectShortCode 
FROM BS_Subject 
WHERE NOT EXISTS 
(SELECT SubjectToClassID FROM BS_SubjectToClass WHERE 
BS_Subject.SubjectID = BS_SubjectToClass.SubjectID 
AND BS_SubjectToClass.ClassID =2) 

Answer 2

- değil <> (yani VB falandır ....)

SELECT 
    DISTINCT(BS_Subject.SubjectID) DepartmentID, 
    SubjectName, SubjectDescription, SubjectShortCode 
FROM dbo.BS_Subject 
WHERE 
    BS_Subject.SubjectID NOT IN 
     (SELECT DISTINCT(BS_Subject.SubjectID) 
     FROM dbo.BS_Subject, dbo.BS_SubjectToClass 
     WHERE BS_Subject.SubjectID = BS_SubjectToClass.SubjectID 
     AND BS_SubjectToClass.ClassID = 2)
