Use RANK() to Get the Top 3 Employees by Order Count
Order Table:
Query Explanation:
-
COUNT(OrderID)counts the number of orders handled by each employee. -
RANK()assigns a rank to employees based on total orders, from highest to lowest. -
RANK()allows ties—if two employees have the same count, they'll share the same rank. -
The outer query filters only the top 3 ranked employees (
rk <= 3), which may return more than 3 rows if there's a tie.
SQL Query:
SELECT *
FROM (
SELECT
EmployeeID,
COUNT(OrderID) AS TotalOrders,
RANK() OVER (ORDER BY COUNT(OrderID) DESC) AS rk
FROM Orders
GROUP BY EmployeeID
) AS RankedEmployees
WHERE rk <= 3;
Output:
