Calculate distance between two points

The calculation of distance between two points using standard spherical geometry can be inaccurate for short distances (ten miles or less) because the sine function of very small angles approaches zero. The haversine approach (http://en.wikipedia.org/wiki/Haversine_formula) turns this around, so it is very accurate at small distances but has larger errors (about ten miles) for points […]

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?
