Example-3 : The SYSDATE function can be used to set value of columns. To demonstrate create a table named DeliveryDetails.

CREATE TABLE DeliveryDetails (
DeliveryId INT AUTO_INCREMENT,
ProductId INT NOT NULL,
ProductName VARCHAR(20) NOT NULL,
Delivered_At TIMESTAMP NOT NULL,
PRIMARY KEY(DeliveryId)
);

Here, we will use SYSDATE function when a delivery will be completed. The value in Delivered_At column will be the value given by SYSDATE Function.

INSERT INTO  
DeliveryDetails(ProductId, ProductName, Delivered_At)
VALUES
(94567, 'Acer Helios', SYSDATE());

Now, checking the DeliveryDetails table :

SELECT * FROM DeliveryDetails;

Output :

DeliveryId	ProductId	ProductName	Delivered_At
1	94567	Acer Helios	2020-11-26 01:40:57
