Question of the Day

The Disabled Index

I run this code on SQL Server 2022. 

CREATE TABLE Drink
(
    drinkid INT NOT NULL
        CONSTRAINT DrinkPK PRIMARY KEY CLUSTERED,
    drinkname VARCHAR(20),
    rating NUMERIC(2, 1)
)
GO

INSERT INTO Drink
(
    drinkid,
    drinkname,
    rating
)
VALUES
(1, 'Margarita', 4.5),
(2, 'Mojito', 4.3),
(3, 'Old Fashioned', 4.7),
(4, 'Martini', 4.4),
(5, 'Cosmopolitan', 4.2)
GO
ALTER INDEX drinkpk ON dbo.drink DISABLE
GO
SELECT * FROM dbo.Drink
GO
What is the result?
