GEO_NEARBY
Returns whether or not the two points are within the distance specified in meters.
Syntax
GEO_NEARBY(lat1 float, lon1 float, lat2 float, lon2 float, distance double) → boolean
- lat1: The latitude of the source location in degrees.
- lon1: The longitude of the source location in degrees.
- lat2: The latitude of the destination location in degrees.
- lon2: The longitude of the destination location in degrees.
- distance: The specified distance between the two points in meters.
Examples
Determine whether the distance from Venice, Italy to Paris, France is within 800,000 meters.SELECT GEO_NEARBY(CAST(45.4408 AS FLOAT), CAST(12.3155 AS FLOAT), CAST(48.8566 AS FLOAT), CAST(2.3522 AS FLOAT), CAST(800000 AS DOUBLE))
-- False
Usage Notes
The lat and lon parameters to this function can only be the FLOAT
data type. The distance parameter can only be the DOUBLE
data type. You must CAST
other data types for lat and lon to FLOAT
and the distance parameter to DOUBLE
. This function calculates the result using the Haversine distance algorithm.
