6 gru 2012 · Assuming your GeoLoc column is of the 'Geography' data type in SQL server, you should be able to use something like this: select t1.*, t2.*, t1.GeoLoc.STDistance(t2.GeoLoc) as DistanceApart from table1 t1 join table2 t2 on (t1.GeoLoc.STDistance(t2.GeoLoc) <= @distanceX)
31 mar 2024 · Microsoft SQL Server offers the STDistance method to calculate the shortest distance between two geography points with high accuracy.
25 sty 2024 · MySQL 8 introduces functions that facilitate these calculations directly within your database. This tutorial explores different approaches to calculate distances between two locations in MySQL 8, concentrating on both the simplicity and complexity of geospatial queries.
When calculating distance between two points in SQL, there are a few different ways to approach the problem depending on your use case. Cartesian Distance (aka Euclidean distance), or the distance on a flat map calculated using a straightforward SQL query.
This stored procedure is using the STDistance function. You can find the distance in Kilometers or Miles. To find the distance in miles use the following code: EXECUTE Distance 'Cochabamba','London','miles'. The distance between these two cities in miles is: 6186.99.
Distances can be approximate if necessary (i.e. between 500m and 1km as a category) but if it's possible to do something more refined that would be great. Data is currently in Mapinfo TAB files. I seek a Mapinfo solution, if possible.
