Detailed Subjects Query

Since the question asks for "Which subjects are taught at Jefferson Middle School?"

Would we not look soley for the NAME? Thus creating a query as below:

SELECT NAME FROM SUBJECTS GROUP BY NAME ORDER BY NAME;

The video answer seemed to call everything form the Table rather than the subjects themselves.

Personally, I consider "7th Grade Math" to be separate from "8th Grade Math" and so on, so I actually went for something similar to the video, but included the grade as well. It can really be interpreted different ways (like many real world problems or practices that emulate them)

Hi Darshen,

You are correct that the video should only select the name, instead of everything in the table, but that is what he did.

I did it a different way, but agree with you in the result.

select distinct(name) from subjects;

I took it even a step farther with the following:

SELECT DISTINCT name AS "Subjects Taught" FROM subjects;
