Question of the Day

Encoding URLs

I have this data in a SQL Server 2025 table:

CREATE TABLE Response
( ResponseID INT NOT NULL CONSTRAINT ResponsePK PRIMARY KEY
, ResponseVal VARBINARY(5000)
)
GO
If I want to get a value from this table that I can add to a URL in a browser, which of these code items produces a result I can use?
