算法:根據(jù)班級狀態(tài)(開課中,尚未開課),搜集班級下面的學員,并且課時未上完,選班狀態(tài)正常。注意:一名學員報多門課程,會被重復統(tǒng)計。

(此查詢針對access版本,SQL版只要將其中的Now()函數(shù)替換為GetDate()即可)

and StuClass.Lessons > StuClass.CourseProgress
and StuClass.ScStateID in (1,2)
and Class.SchoolID in ( {@SchoolID:校區(qū)} )
and ((Class.EndDate > Now() and Class.StartDate < Now()) or Class.StartDate > Now())


子查詢:
