问题
I tried to find the UDF dbo.fn_calculateJaroWinkler (for computing the Jaro Winkler distance) for sql server and couldn't find it. Does anyone wrote it and could share?

You may have to join sqlservercentral to view the page. There is a step by step explanation here on how to create the functions. I am actually using it myself now to do fuzzy logic. It works but it is a bit slow for large data sets. If you have any optimization tricks let me know!
