Creates a DbFunctionExpression that invokes the canonical 'SpatialSymmetricDifference' 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.

[System::Runtime::CompilerServices::Extension]

public static System.Data.Common.CommandTrees.DbFunctionExpression SpatialSymmetricDifference (this System.Data.Common.CommandTrees.DbExpression spatialValue1, System.Data.Common.CommandTrees.DbExpression spatialValue2);

<Extension()>
Public Function SpatialSymmetricDifference (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 symmetric difference with spatialValue1 should be computed.

Returns

DbFunctionExpression

A new DbFunctionExpression that returns the geometry value representing the symmetric difference of spatialValue2 with spatialValue1.
