Visual SQL Relational JOIN Laboratory

Executing SQL Query:

SELECT s.id, s.name, s.major, e.course, e.grade
FROM students s
INNER JOIN enrollments e
  ON s.id = e.student_id;

Left Table: students (s)

id (PK)	name	major
1	Aarav	CS
2	Diya	AI
3	Kabir	Data
4	Riya	Cyber

Right Table: enrollments (e)

student_id (FK)	course	grade
1	CS301	A
2	CS301	B+
2	CS304	A+
5	CS305	A

Relational Result Set (3 rows returned)Matched by s.id = e.student_id

s.id	s.name	s.major	e.course	e.grade
1	Aarav	CS	CS301	A
2	Diya	AI	CS301	B+
2	Diya	AI	CS304	A+

Relational Join Invariant:

In INNER JOIN: Only rows with matching keys in BOTH tables are preserved. Any unmatched student (like Kabir or Riya) or unmatched enrollment (like Student 5) is completely omitted.
