SQL Server return type: nvarchar(4000)

CLR return type: SqlString

Remarks

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

Examples

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((0 0, 3 0, 3 3, 0 3, 0 0))', 0);  
SELECT @g.STGeometryType();
