SpatialEdmFunctions.GeometryPointFromText(DbExpression, DbExpression) Method

Definition

Creates a DbFunctionExpression that invokes the canonical 'GeometryPointFromText' function with the specified arguments. pointWellKnownText must have a string result type, while coordinateSystemId must have an integer numeric result type. The result type of the expression is Edm.Geometry.

public:
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeometryPointFromText(System::Data::Common::CommandTrees::DbExpression ^ pointWellKnownText, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);
public static System.Data.Common.CommandTrees.DbFunctionExpression GeometryPointFromText (System.Data.Common.CommandTrees.DbExpression pointWellKnownText, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);
static member GeometryPointFromText : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression
Public Function GeometryPointFromText (pointWellKnownText As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

Parameters

pointWellKnownText
DbExpression

An expression that provides the well known text representation of the geometry point value.

coordinateSystemId
DbExpression

An expression that provides the coordinate system id (SRID) of the geometry point value's coordinate system.

Returns

A new DbFunctionExpression that returns a new geometry point value based on the specified values.

Exceptions

pointWellKnownText coordinateSystemId

pointWellKnownText coordinateSystemId
