Why don't we just use INNER JOIN instead of INTERSECT?
Why don't we just use INNER JOIN instead of INTERSECT since they do, I think, the same thing?

They can have the same final result; but a
JOIN adds an additional source to a single query based on specific matching criteria, and
INTERSECT combines two complete queries (two
SELECTs) that return identical columns.
