SqlGeometry.STDifference Method
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
'Declaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Function STDifference ( _
other As SqlGeometry _
) As SqlGeometry
'Usage
Dim instance As SqlGeometry
Dim other As SqlGeometry
Dim returnValue As SqlGeometry
returnValue = instance.STDifference(other)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeometry STDifference(
SqlGeometry other

public:

member STDifference :
other:SqlGeometry -> SqlGeometry
public function STDifference(
other : SqlGeometry
) : SqlGeometry
Parameters
- other
Type: Microsoft.SqlServer.Types.SqlGeometry
The SqlGeometry instance indicating which points to remove from the instance on which STDifference is being invoked.
Return Value
Type: Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents the unique points in the calling SqlGeometry.
Remarks
This method always returns nulla null reference (Nothing in Visual Basic) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match.
