MySQL: DEFAULT constraint is easy

[@BroCodez]

- EXAMPLE 1
CREATE TABLE products (
product_id INT,
product_name varchar(25),
price DECIMAL(4, 2) DEFAULT 0
);
ALTER TABLE products
ALTER price SET DEFAULT 0;
INSERT INTO products (product_id, product_name)
VALUES (104, "straw"),
(105, "napkin"),
(106, "fork"),
(107, "spoon");
SELECT * FROM products;
- EXAMPLE 2
CREATE TABLE transactions(
transaction_id INT,
amount DECIMAL(5, 2),
transaction_date DATETIME DEFAULT NOW()
);
SELECT * FROM transactions;
INSERT INTO transactions (transaction_id, amount)
VALUES (1, 4.99);
SELECT * FROM transactions;
INSERT INTO transactions (transaction_id, amount)
VALUES (2, 2.89);
SELECT * FROM transactions;
INSERT INTO transactions (transaction_id, amount)
VALUES (3, 8.37);
SELECT * FROM transactions;
DROP TABLE transactions;

Why did you use ALTER instead of MODIFY? 03:40

[@dixsonjoy5394]

I also have this doubt

[@apoorvsxna]

This would also work-
ALTER TABLE products
MODIFY price DECIMAL (5,2) DEFAULT 0.00;
