GeomFromGml (geometry Data Type)

 

Construct a geometry instance given a representation in the SQL Server subset of the Geography Markup Language (GML).

For more information on the Geography Markup Language, see the following Open Geospatial Consortium Specifications:

OGC Specifications, Geography Markup Language

Applies to: SQL Server (SQL Server 2008 through current version), Azure SQL Database.
  
GeomFromGml ( GML_input, SRID )  

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

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

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="http://www.opengis.net/gml"> <posList>100 100 20 180 180 180</posList> </LineString>';  
SET @g = geometry::GeomFromGml(@x, 0);  
SELECT @g.ToString();
