STAsBinary (geography Data Type)

Returns the Open Geospatial Consortium (OGC) Well-Known Binary (WKB) representation of a geography instance.

This geography data type method supports FullGlobe instances or spatial instances that are larger than a hemisphere.

.STAsBinary ( )

SQL Server return type: varbinary(max)

CLR return type: SqlBytes

The OGC type of a geography instance can be determined by invoking STGeometryType().

The following example uses STAsBinary() to create a LineString geography instance from (-122.360, 47.656) to (-122.343, 47.656) from text. It then returns the result in WKB.

DECLARE @g geography;
SET @g = geography::STGeomFromText('LINESTRING( -122.360 47.656, -122.343 47.656)', 4326);
SELECT @g.STAsBinary();
