GeomFromGml ( GML_input, SRID )  


Is an XML input from which the GML will return a value.

Is an int expression representing the spatial reference ID (SRID) of the geometry instance you wish to return.

Return Types

SQL Server return type: geometry

CLR return type: SqlGeometry


This method will throw a FormatException if the input is not well-formatted.


The following example uses GeomFromGml() to create a geometry instance.

DECLARE @g geometry;  
DECLARE @x xml;  
SET @x = '<LineString xmlns=""> <posList>100 100 20 180 180 180</posList> </LineString>';  
SET @g = geometry::GeomFromGml(@x, 0);  
SELECT @g.ToString();
