Paramètres
- other
Type : Microsoft.SqlServer.Types. . :: . .SqlGeometry
The SqlGeometry instance indicating which points to remove from the instance on which STDifference is being invoked.
Valeur de retour
Type : Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry object that represents the unique points in the calling SqlGeometry.
Notes
This method always returns null Nothing nullptr unit une référence Null (Nothing dans Visual Basic) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
