Yes, all of the row counts make sense, there may be some duplicatoin.
|
||||
For example, when we are getting all student ids, and their enrollments, there may be duplicate enrollment data.
|
||||
i.e. two students are enrolled in the same course_offering. However, we since we are showing the student_id we are able to tell them apart.

I dont think distinct would change the result in the example above, there is student x enrolled in class A, and student y enrolled in class A too. Those are already distinct.
|

I think for the most part I am selecting the minimul necessary columns, only showing relavent related information.

||||
Unless asked to show all data of a table.
