CREATE TABLE CustomerPurchases ( CustomerID INT, PurchaseDate DATE, SaleAmount DECIMAL(10, 2) );
-- Insert Records for CustomerPurchases
INSERT INTO CustomerPurchases (CustomerID, PurchaseDate, SaleAmount) VALUES (1, '2023-01-01', 100.00), (2, '2023-01-01', 50.00), (3, '2023-01-01', 20.00), (4, '2023-01-01', 150.00), (5, '2023-01-01', 60.00), (1, '2023-01-02', 110.00), (2, '2023-01-02', 90.00), (6, '2023-01-02', 40.00), (7, '2023-01-02', 80.00), (8, '2023-01-02', 70.00), (9, '2023-01-03', 100.00), (10, '2023-01-03', 50.00), (11, '2023-01-03', 30.00), (12, '2023-01-03', 120.00), (13, '2023-01-03', 110.00), (14, '2023-01-04', 75.00), (15, '2023-01-04', 65.00), (16, '2023-01-04', 55.00), (17, '2023-01-04', 45.00), (18, '2023-01-04', 35.00), (19, '2023-01-05', 95.00), (20, '2023-01-05', 85.00), (1, '2023-01-05', 75.00), (2, '2023-01-05', 65.00)

Just found you. Great examples. The more complex the better.
One suggestion. If you can show a user interface (created in anything you feel comfortable-VBA-Excel, CSharp, Python, Access etc having a connection to the database/tables) for data input/entry, with a nice data validation, would be really a break-through.

[@SidraCodes-LetsGo]

Thank you for your kind words. Your suggestion is noted.. I will for sure in the upcoming videos.
