STDifference-Methode
Returns an object that represents the points from one SqlGeometry instance that do not lie within another SqlGeometry instance.
Namespace: Microsoft.SqlServer.Types
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
Syntax

'Usage
Dim instance As SqlGeometry

public function STDifference(
other : SqlGeometry
) : SqlGeometry
Parameter
- other
Typ: Microsoft.SqlServer.Types. . :: . .SqlGeometry
The SqlGeometry instance indicating which points to remove from the instance on which STDifference is being invoked.
Rückgabewert
Typ: Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry object that represents the unique points in the calling SqlGeometry.
Hinweise
This method always returns null Nothing nullptr unit ein NULL-Verweis (Nothing in Visual Basic) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
