I started my SQL journey here at SQLServerCentral as one of the founders, helping to build a place to share and learn that continues to thrive under the editorial guidance of my friend Steve Jones. I've done a lot of volunteer work over the years ranging from our local SQL group (oPASS, SQLOrlando) to serving on the Board of Directors of PASS to designing and building the framework of SQLSaturday (which has gone on to produce more than 1000 locally managed events since we started in 2007). These days I manage a DBA team, but over the years I've been a trainer, consultant, contractor, and DBA. I'm rarely present on social media, the best way to contact me is here, LinkedIn, or via email.

Mo-SQL

If you’re involved in the database world it’s hard to have missed the rise of the “no-sql” database products, designed to – depending on your view or the product I suppose – make databases simpler, break out of the transaction database paradigm, scale out across hundreds of machines, make it easy to change the db design (or not require one). I think some of the problems no-sql tries to solve are real, others reflect a lack of awareness/training/tools on how and why relational databases could not just solve the problem, but solve it better.

Question of the Day

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?
