ST_PointFromGeoJSON

ST_PointFromGeoJSON takes a string column and returns a point column. The input string column must contain the GeoJSON representation of point geometries. You can optionally specify a spatial reference for the result point column. The sr parameter value must be a valid SRID or WKT string. If a point cannot be created from the input string the function will return null.

For more details, go to the GeoAnalytics for Microsoft Fabric API reference for point_from_geojson.
