반환 값
유형: Microsoft.SqlServer.Types.SqlGeography
A SqlGeography representing the specified point in the calling instance.
주의
If a SqlGeography instance is user-created, the STPointN method returns the point specified by expression by ordering the points in the order in which they were originally input.
If a SqlGeography instance is constructed by the system, STPointN returns the point specified by expression by ordering all the points in the same order they would be output: first by geography instance, then by ring within the instance (if appropriate), and then by point within the ring. This order is deterministic.
If this method is called with a value less than 1, it throws an ArgumentOutOfRangeException.
If this method is called with a value greater than the number of points in the instance, it returns nullnull 참조(Visual Basic에서는 Nothing).
