Examples

The following example creates a LineString instance and uses AsGML() to return the GML description of the instance.

DECLARE @g geometry;  
SET @g = geometry::STGeomFromText('LINESTRING(0 0, 0 1, 1 0)', 0)  
SELECT @g.AsGml();  

This method returns the description as a LineString instance.

<LineString xmlns="http://www.opengis.net/gml">  
<posList>0 0 0 1 1 0</posList></LineString>
