STPointOnSurface (geometry Data Type)

SQL Server 2012

Returns an arbitrary point located within the interior of a geometry instance.

Copy 
.STPointOnSurface ( )

SQL Server return type: geometry

CLR return type: SqlGeometry

Open Geospatial Consortium (OGC) type: Point

This method returns null if the instance is empty.

The following example creates a Polygon instance and uses STPointOnSurface() to find a point on the instance.

Copy 
DECLARE @g geometry;
SET @g = geometry::STGeomFromText('POLYGON((0 0, 3 0, 3 3, 0 3, 0 0),(2 2, 2 1, 1 1, 1 2, 2 2))', 0);
SELECT @g.STPointOnSurface().ToString();
