STGeometryN (geometry Data Type)

Returns a specified geometry in a geometry collection.


.STGeometryN (expression)


  • expression
    Is an int expression between 1 and the number of geometry instances in the geometrycollection.

Return Types

SQL Server return type: geometry

CLR return type: SqlGeometry


This method returns null if the parameter is larger than the result of STNumGeometries() and will throw an ArgumentOutOfRangeException if the expression parameter is less than 1.


The following example creates a MultiPointgeometry collection and uses STGeometryN() to find the second geometry instance of the collection.

DECLARE @g geometry;
SET @g = geometry::STGeomFromText('MULTIPOINT(0 0, 13.5 2, 7 19)', 0);
SELECT @g.STGeometryN(2).ToString();
