Parâmetros
- other
Tipo: Microsoft.SqlServer.Types. . :: . .SqlGeometry
The SqlGeometry instance indicating which points to remove from the instance on which STDifference is being invoked.

A SqlGeometry object that represents the unique points in the calling SqlGeometry.
Comentários
This method always returns null Nothing nullptr unit uma referência nula (Nothing no Visual Basic) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
