Question of the Day

Using CHOOSE()

We have this code that sets some status values and then queries them using the CHOOSE() function in SQL Server 2025.

CREATE TABLE Status
(
    StatusID INT,
    StatusDescription VARCHAR(20)
);
GO
INSERT dbo.Status
(
    StatusID,
    StatusDescription
)
VALUES
(0, 'Uncategorized'),
(1, 'Active'),
(2, 'Inactive'),
(3, 'Temp');

GO
SELECT CHOOSE(StatusID, 'Unknown', 'Active', 'Inactive', 'Temporary')
FROM Status;
When the SELECT runs, what is returned?
