[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance FabricSQLDB]
Returns the Open Geospatial Consortium (OGC) type name represented by a geometry instance.
.STGeometryType ( )
[!INCLUDEssNoVersion] 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, and MultiPolygon.
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();
