SpatialEdmFunctions.SpatialDifference(DbExpression, DbExpression) Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Creates a DbFunctionExpression that invokes the canonical 'SpatialDifference' function with the specified arguments, which must each have an Edm.Geography or Edm.Geometry result type. The result type of spatialValue1
must match the result type of spatialValue2
. The result type of the expression is the same as the type of spatialValue1
and spatialValue2
.

<Extension()>
Public Function SpatialDifference (spatialValue1 As DbExpression, spatialValue2 As DbExpression) As DbFunctionExpression
Parameters
- spatialValue1
- DbExpression
An expression that specifies the first spatial value.
- spatialValue2
- DbExpression
An expression that specifies the spatial value for which the difference with spatialValue1
should be computed.
Returns
A new DbFunctionExpression that returns the geometry value representing the difference of spatialValue2
with spatialValue1
.
Exceptions
spatialValue1
spatialValue2
spatialValue1
spatialValue2
