SELECt FirstName FROM Employees E INNER JOIN Orders O ON E.EmployeeID = O.EmployeeID (SELECT Count(EmployeeID) EmployeeCount FROM Orders GROUP BY EmployeeID)

Answer 1

Select TOP 1 WITH TIES FirstName, Count(OrderID) 
FROM Employees e 
INNER JOIN Orders o on e.EmployeeID = o.EmployeeID 
GROUP BY FirstName
ORDER BY Count(OrderID) DESC

Should doo the trick
