Return Types

SQL Server return type: varbinary(max)

CLR return type: SqlBytes

Remarks

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

Examples

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();
