Pablo Echeverria

I've worked for more than 10 years as a software programmer and analyst, during which time I studied parallel programming and became a senior programmer specialist. In 2016, I switched jobs to a DBA position, where I've implemented new processes and created better monitoring tools, while I'm growing my data scientist skills to improve my customer's businesses.

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?
