Returns the number of geometries that make up a geography instance.
.STNumGeometries ( )
SQL Server return type: int
CLR return type: SqlInt32
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.
The following example creates a MultiPoint instance and uses STNumGeometries() to find out how many geometries the instance contains.
MultiPoint
STNumGeometries()
DECLARE @g geography; SET @g = geography::STGeomFromText('MULTIPOINT((-122.360 47.656), (-122.343 47.656))', 4326); SELECT @g.STNumGeometries();
