这是查询错误所指向的，不知道出了什么问题？

SELECT ISNULL(SUM(a.classes),0) 
from (SELECT DISTINCT a.for_date, COUNT(DISTINCT classID) as classes 
      FROM School_Classes sc 
      INNER JOIN app_attendance a on a.schoolclass_id = sc.Id 
      WHERE schoolID =@SchoolID AND a.for_date BETWEEN 
      DATEADD(DAY,-30,getdate()) AND getdate() GROUP BY a.for_date
      ) a
