MS Access SQL that shows courses NOT TAKEN by student before
问题 I have tried many ways, and i suspect NOT EXIST may help, but i am not sure how to implement the SQL statement. Someone help me please? I have three tables in MS Access database. Students (Student Name, Email) Courses (Course Name, Fees) Registration (Course Name, Student Name) I want to now create a Query that can show me all classes that each student HAS NOT taken before. This will allow my Registration Manager to pursue them to perform more class registration. How can I easy do this in MS
