[System::Runtime::CompilerServices::Extension]
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ SpatialConvexHull(System::Data::Common::CommandTrees::DbExpression ^ geometryValue);

public static System.Data.Common.CommandTrees.DbFunctionExpression SpatialConvexHull (this System.Data.Common.CommandTrees.DbExpression geometryValue);

static member SpatialConvexHull : System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression

<Extension()>
Public Function SpatialConvexHull (geometryValue As DbExpression) As DbFunctionExpression

Parameters

geometryValue: DbExpression

An expression that specifies the geometry value from which the convex hull value should be retrieved.

Returns

DbFunctionExpression

A new DbFunctionExpression that returns the convex hull for geometryValue.
