Well done, exactly how I would have done it.
| INSERT INTO Products (SupplierID, CategoryID) VALUES (1, 3); | ||
| INSERT INTO Products (SupplierID, CategoryID) VALUES (2, 1); | ||
| INSERT INTO Products (SupplierID, CategoryID) VALUES (2, 4); | ||

This works. You could also have done something like below:
INSERT INTO Products
VALUES
(NULL, "Hot Chesse", 1, 1, "1 kg pkg", 30.85),
(NULL, "Nachos", 1, 1, "2kg pkg", 60.55),
(NULL, "Taco Tortilla", 1, 1, "5 kg pkg", 200);
| (5) Update the two top rows of the Products Table to increase the price by 1.50. (Get SQL to do the addition for you.) Paste your SQL statement below. | ||
|
|
||
| UPDATE Products SET price = price + 1.50 WHERE ProductID IN ( SELECT ProductID from Products LIMIT 2); | ||
|

This works. In this case your where condition could be simplified to WHERE ProductID IN (1, 2). However, the way you did it does show how subqueries can be used.
|
|
||
| (6) Delete all rows of the Products Table where the price is less than 7.00. Paste your SQL statement below. | ||
|
|
||
| DELETE FROM Products WHERE price < 7.00; No newline at end of file |
