[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance FabricSQLDB]
Construct a geometry instance given a representation in the [!INCLUDEssNoVersion] 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
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.
[!INCLUDEssNoVersion] 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();
