How Filters and Sorting can Derail SQL Pagination Performance

In my previous tip, Pagination Performance in SQL Server, I showed how to make SQL pagination more predictable – turning O(n) into O(1). I materialized and cached row numbers to page through instead of calculating them on every request. It wasn’t the whole story, though; real pagination queries rarely get to sort without filtering. Users always want more control, and filtering can threaten that predictability.

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?
