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 nullune référence Null (Nothing dans Visual Basic) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
