如何找到当前点纬度和纬度附近的区域

Question

I have a point with latitude and longitude as (current place). In my Database, I have many points (lat & long) which show me stores (for example). I need a SQL Server query to get stores which are near my current place with 5 Kilometers distance.

Answer 1

使用STDistance方法：

SELECT * FROM dbo.MyTable WHERE Location.STDistance(@CurrentPlace) <= 5000;
