반환 값
유형: System.Data.SqlTypes.SqlInt32
Returns 1 if the SqlGeometry instance is not a MultiPoint, MultiLineString, MultiPolygon, or GeometryCollection instance, and 0 if the SqlGeometry instance is empty.
주의
If a geometry collection has nested empty elements, STNumGeometries will not return 0. Though the elements in the geometry collection instance are empty, the instance itself is not an empty set.
