Return Types

SQL Server return type: nvarchar(4000)

CLR return type: SqlString


The OGC type names that can be returned by STGeometryType() are Point, LineString, CircularString, CompoundCurve, Polygon, CurvePolygon, GeometryCollection, MultiPoint, MultiLineString, MultiPolygon, and FullGlobe.


The following example creates a Polygon instance and uses STGeometryType() to confirm that it is a polygon.

DECLARE @g geometry;  
SET @g = geometry::STGeomFromText('POLYGON((-122.358 47.653, -122.348 47.649, -122.348 47.658, -122.358 47.658, -122.358 47.653))', 4326);  
SELECT @g.STGeometryType();
