For each dealership, rank employees by total sales amount in descending order. In the results I want to see dealership_name, employee_name , total_sales and sales_rank

SELECT d.name AS dealership_name, e.name AS employee_name, SUM(s.sale_price) AS total_sales, RANK() OVER (PARTITION BY d.branch_id ORDER BY SUM(s.sale_price) DESC) AS sales_rank FROM sales s JOIN employees e ON s.employee_id = e.employee_id JOIN dealerships d ON s.branch_id = d.branch_id GROUP BY d.name, e.name, d.branch_id;

WITH EmployeeSales AS (
    SELECT 
        d.branch_id,
        d.name AS dealership_name,
        e.employee_id,
        e.name AS employee_name,
        COALESCE(SUM(s.sale_price), 0) AS total_sales
    FROM 
        dealerships d
    JOIN 
        employees e ON d.branch_id = e.branch_id
    LEFT JOIN 
        sales s ON e.employee_id = s.employee_id AND d.branch_id = s.branch_id
    GROUP BY 
        d.branch_id, d.name, e.employee_id, e.name
)
SELECT 
    dealership_name,
    employee_name,
    total_sales,
    RANK() OVER (PARTITION BY branch_id ORDER BY total_sales DESC) AS sales_rank
FROM 
    EmployeeSales
ORDER BY 
    dealership_name, sales_rank;
