The Performance of Traversing a SQL Hierarchy

  • Article

Dwain Camps shows that, depending on the size and characteristics of some hierarchical data, six different methods of traversal can each be the fastest at some point.

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?
