How to use sys.fn_PhysLocFormatter undocumented function

It would be nice if we could use the DBCC PAGE command to see exactly what it is stored at the page level, however, in order to do this we need to find a way to correlate the results returned from a SELECT statement with the physical data location. Is that possible? The answer is: YES. All we need to do is use the sys.fn_physLocFormatter function. In this tip, I will cover how to use this undocumented function.

PASS AppDev Presents: SQL Server Indexing

While indexing traditionally has been the concern of the DBA, it's important for developers to understand both the usefulness and the impact of indexes in your relational database. With the right indexes your application will perform like a Formula One racer, without them performance will better resemble a Model T. This presentation will explain how indexes work, what options are available to you in SQL Server 2008, and how to tune your application and your database for the best performance.By Allen White, 2/9/2010, 1:00EST

Missing the Jaro Winkler Distance

I upgraded a SQL Server 2019 instance to SQL Server 2025. I wanted to test the fuzzy string search functions. I run this code:

SELECT JARO_WINKLER_DISTANCE('tim', 'tom')
I get this error message:
Msg 195, Level 15, State 10, Line 1 'JARO_WINKLER_DISTANCE' is not a recognized built-in function name.
What is wrong?
