Creates a DbFunctionExpression that invokes the canonical 'SpatialRelate' function with the specified arguments, which must have Edm.Geometry and string result types. The result type of the expression is Edm.Boolean.
public static System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpression SpatialRelate (this System.Data.Entity.Core.Common.CommandTrees.DbExpression geometryValue1, System.Data.Entity.Core.Common.CommandTrees.DbExpression geometryValue2, System.Data.Entity.Core.Common.CommandTrees.DbExpression intersectionPatternMatrix);static member SpatialRelate : System.Data.Entity.Core.Common.CommandTrees.DbExpression * System.Data.Entity.Core.Common.CommandTrees.DbExpression * System.Data.Entity.Core.Common.CommandTrees.DbExpression -> System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpression<Extension()>
Public Function SpatialRelate (geometryValue1 As DbExpression, geometryValue2 As DbExpression, intersectionPatternMatrix As DbExpression) As DbFunctionExpressionParameters
- geometryValue1
- DbExpression
An expression that specifies the first geometry value.
- geometryValue2
- DbExpression
An expression that specifies the geometry value that should be compared with geometryValue1.
- intersectionPatternMatrix
- DbExpression
An expression that specifies the text representation of the Dimensionally Extended Nine-Intersection Model (DE-9IM) intersection pattern used to compare geometryValue1 and geometryValue2.
Returns
A new DbFunctionExpression that returns a Boolean value indicating whether geometryValue1 is spatially related to geometryValue2 according to the spatial relationship designated by intersectionPatternMatrix.
