I wrote about finding distance between two location in my older post. I have been getting question about how to make the search by using data in SQL Server. In this post, I will try to answer all these questions. You do not need to have latest version of SQL Server to do any of these examples. SQL Server has been supporting Geospatial data since 2008.
First, we need some data. Not just some data, some free spatial data. I want to show you how to find distance between cities in this post, so I need at least names of the cities and their latitude and longitude. I downloaded this data from SimpleMaps website in CSV Format.
Read on for the solution.
