Creates a DbFunctionExpression that invokes the canonical 'SpatialUnion' 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.

Public Function SpatialUnion (spatialValue1 As DbExpression, spatialValue2 As DbExpression) As DbFunctionExpressionParameters
- spatialValue1
- DbExpression
An expression that specifies the first spatial value.
- spatialValue2
- DbExpression
An expression that specifies the spatial value for which the union with spatialValue1 should be computed.
Returns
A new DbFunctionExpression that returns the spatial value representing the union of spatialValue1 and spatialValue2.
