Say I want to select max and min numb and there ids from above tabl in single select statement e.x select min(numb) ,id –(id for that (min (numb)))
,max(numb),id –(id for that (max (numb)))
from tabl –actual table is consist of 100000 number so how can we achieve it in single select statement.

Question2nd:

How it can be done

Bit unusual question but see how we go?
