T-SQL: Stored Procedures (DELETE), DELETE An Existing Northwind Product Part 3

To create the delete procedure type in the following code in the SQL editor window in "Microsoft SQL Server Management Studio"

USE Northwind
GO
CREATE PROCEDURE dbo.delProduct @ProductID int
AS
DELETE FROM Products
WHERE Products.ProductID = @ProductID
GO

The stored procedure only takes in one input parameter which is the ProductID, the DELETE statement needs a ProductID because if there is no WHERE clause, every record in the product in the Products table will be deleted. Make sure you backup the table before you work with a DELETE stored procedure.
Here is how would execute the stored procedure
EXEC dbo.delProduct 78
