ST_DISTANCE (Azure Stream Analytics)
Returns the geodesic distance between two points in meters. Cartesian distances require projection calculations and are not supported, but they can be implemented in user defined functions. If used with Polygons will return 0.
Syntax
ST_DISTANCE ( pointA, pointB )
Argument
PointA
The point to measure distance from.
PointB
The point to measure distance to.
Return Type
Returns the distance between two points in meters.
Example
SELECT
ST_DISTANCE(input.carPosition, input.warehouse)
FROM input
Input Example
carPosition | warehouse |
---|---|
{"type":"Point", "coordinates": [-5.0, -5.0]} | {"type":"Point", "coordinates": [0.0, 0.0]} |
Output Example
784028.74077501823
