I am trying to make a KML file using SQL for XML to path. But I need another "root" section named "Folder" below KML. Everything I try makes another section named folder for every sub-section.
with xmlnamespaces (
'http://www.w3.org/2005/Atom' as Atom,
'http://www.opengis.net/kml/2.2' as kml,
'http://www.google.com/kml/ext/2.2' as gx,
default 'http://www.opengis.net/kml/2.2'
)
select --'kml' as kml,
--'NewSpots 2013' as 'Folder/Name',
--Waypoint as 'Folder/Placemark/name',
--Description as 'Folder/Placemark/description',
--ProperDecimalGPS as 'Folder/Placemark/Point/coordinates'
Waypoint as 'Placemark/name',
Description as 'Placemark/description',
ProperDecimalGPS as 'Placemark/Point/coordinates'
--WPGroup as 'Folder/Name'
from dbo.ttt
where PortArea = 'NewSpots 2013'
for xml path(''), root('kml')
Here is the output. I need the sections as they show in reults below, but those items are commented out to easily see what I am missing/needing.
<kml xmlns="http://www.opengis.net/kml/2.2"
xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:Atom="http://www.w3.org/2005/Atom">

If you need the design of ttt table...
USE [Fishing]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[ttt](
[PortArea] [varchar](50) NULL,
[WPGroup] [varchar](150) NULL,
[Waypoint] [varchar](150) NULL,
[ProperDecimalGPS] [varchar](50) NULL,
[Description] [varchar](max) NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO
Some Sample data :
Try it like this
Short explanation: It would be possible, to pack all-in-one, but in this case you'd see the namespace declarations repeatedly (each Placemark
would be a *sub-select). This is not wrong but annoying (see this related answer)
My solution: Create the XML in two steps and only the last one with namespaces
CREATE TABLE [dbo].[ttt](
[PortArea] [varchar](50) NULL,
[WPGroup] [varchar](150) NULL,
[Waypoint] [varchar](150) NULL,
[ProperDecimalGPS] [varchar](50) NULL,
[Description] [varchar](max) NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY];
GO
INSERT INTO dbo.ttt VALUES
('NewSpots 2013','106 Rok','106 Rok-1','-94.271833,28.633483,0',NULL)
,('NewSpots 2013','106 Rok','106 Rok-2','-94.269783,28.649767,0',NULL)
,('NewSpots 2013','106 Rok','106 Rok-3','-94.269033,28.6336,0',NULL);
GO
DECLARE @FolderName VARCHAR(MAX)='NewSpots 2013';
DECLARE @Placemarks XML;
SELECT @Placemarks=
(
select Waypoint as 'name',
Description as 'description',
ProperDecimalGPS as 'Point/coordinates'
from dbo.ttt
where PortArea = @FolderName
for xml path('Placemark'),TYPE
);
with xmlnamespaces (
'http://www.w3.org/2005/Atom' as Atom,
'http://www.opengis.net/kml/2.2' as kml,
'http://www.google.com/kml/ext/2.2' as gx,
default 'http://www.opengis.net/kml/2.2'
)
SELECT @FolderName AS 'Name'
,@Placemarks
FOR XML PATH('Folder'),ROOT('kml')
GO
--Clean-up
--DROP TABLE dbo.ttt;
The result
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:Atom="http://www.w3.org/2005/Atom">
<Folder>
<Name>NewSpots 2013</Name>
<Placemark xmlns="">
<name>106 Rok-1</name>
<Point>
<coordinates>-94.271833,28.633483,0</coordinates>
</Point>
</Placemark>
<Placemark xmlns="">
<name>106 Rok-2</name>
<Point>
<coordinates>-94.269783,28.649767,0</coordinates>

Due to xmlns=""
in the nested elements this elements are not living in the same default namespace!
The only solution seems to be a cast to nvarchar(max)
, then a REPLACE()
to get rid of these xmlns=""
declarations and then a re-cast to XML. I hope that this will be solved in a future version!
