Remarks

This method returns 1 if the geography instance is not a MultiPoint, MultiLineString, MultiPolygon, or GeometryCollection instance, or 0 if the geography instance is empty.

Examples

The following example creates a MultiPoint instance and uses STNumGeometries() to find out how many geometries the instance contains.

DECLARE @g geography;  
SET @g = geography::STGeomFromText('MULTIPOINT((-122.360 47.656), (-122.343 47.656))', 4326);  
SELECT @g.STNumGeometries();
