Question

I have two columns A and B. I want to select the value of column A where B has its maximum value.

SELECT MAX(B) FROM table_name

just gives me the value of B.

I can do another query with the value of B to get A, but is there a shorter way with just one SQL query?

Answer 1

select A
from MyTable 
where B = (SELECT MAX(B) FROM MyTable)

or

select t.A
from MyTable t
inner join (
    SELECT MAX(B) as BMAX FROM MyTable
) tm on t.B = t.BMAX
