🚀 Master SQL for Interviews! 📊
💡 SQL Challenge: Ready to test your skills? Here’s a commonly asked SQL Interview Question that you must know to ace your next job interview! 👇
🔥 Question:
Write a SQL query to calculate the cumulative sum of sales for each employee. The result should include:
👉 EmployeeID
👉 SaleDate
👉 CumulativeSales
--SQL Code to Create the Table:
CREATE TABLE Sales (
EmployeeID INT,
SaleDate DATE,
SaleAmount DECIMAL(10, 2)
);
--Insert Sample Data into the Table
INSERT INTO Sales (EmployeeID, SaleDate, SaleAmount) VALUES
(1, '2024-01-01', 100.00), -- Employee 1 made a sale of 100 on Jan 1
(1, '2024-01-02', 150.00), -- Employee 1 made another sale on Jan 2
(1, '2024-01-03', 200.00), -- Employee 1 made another sale on Jan 3
(2, '2024-01-01', 120.00), -- Employee 2 made a sale on Jan 1
(2, '2024-01-02', 180.00), -- Employee 2 made another sale on Jan 2
(3, '2024-01-01', 200.00), -- Employee 3 made a sale on Jan 1
(3, '2024-01-03', 100.00), -- Employee 3 made a sale on Jan 3
(3, '2024-01-04', 50.00); -- Employee 3 made another sale on Jan 4
✨ Here’s the SQL Query Solution:
WITH CumulativeSales AS (
SELECT
EmployeeID,
SaleDate,
SaleAmount,
(SELECT SUM(SaleAmount)
FROM Sales AS S2
WHERE S2.EmployeeID = S1.EmployeeID
AND S2.SaleDate <= S1.SaleDate) AS CumulativeSales
FROM Sales S1
)
SELECT
EmployeeID,
SaleDate,
SaleAmount,
CumulativeSales
FROM CumulativeSales
ORDER BY EmployeeID, SaleDate;
