SpatialEdmFunctions.GeographyMultiPointFromText Method

Definition

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

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

Parameters

multiPointWellKnownText
DbExpression

An expression that provides the well known text representation of the geography multi-point value.

coordinateSystemId
DbExpression

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

Returns

A new DbFunctionExpression that returns a new geography multi-point value based on the specified values.

Exceptions

multiPointWellKnownText coordinateSystemId

multiPointWellKnownText coordinateSystemId
