Table A

tableAID
tableBID
grade

Table B

tableBID
name
description

Table A links to Table b from the tableBID found in both tables.

If I want to find the row in Table A, which has the highest grade, for each row in Table B, I would write my query like this:

select max(grade) from TableA group by tableBID

However, I don't just want the grade, I want the grade plus id of that row.
