매개 변수
- other
유형: Microsoft.SqlServer.Types.SqlGeometry
The SqlGeometry instance indicating which points to remove from the instance on which STDifference is being invoked.
반환 값
유형: Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents the unique points in the calling SqlGeometry.
주의
This method always returns nullnull 참조(Visual Basic에서는 Nothing) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
