This is the query image:
This result should appear as follows:
This is my query: select id, name, total where student.id= marks.sutdent_id
You should group on the student id and name and sum the marks:
SELECT s.id, s.name, SUM(e.marks) AS total
FROM student s
JOIN exam e ON s.id = e.stud_id
GROUP BY s.id, s.name

How can I write a SQL query that will replace the "ComputerID" and "PartID" with the "UnitNumber". The ComputerID's and PartID's are in the same column under InventoryID. The InventoryID's are unique but the UnitNumber (sticker label/name) doesn't have this requirement.
Here are the tables and how they relate.
Let's call your tables Object and Inventory
If you use a couple of joins then this should work:
select o.ObjectID as ObjectID, a.UnitNumber as Computer, b.UnitNumber as Part,
o.InputID from Object o
join Inventory a on a.InventoryID=o.CombputerID
join Inventory b on b.InventoryID=o.PartID
