My SQL Query generates a XML output:
select 'TEST.kml' as name,
(select 'TEST' as name, (
select (
select top 10 issue as name,
null as description,
null as 'Point/coordinates',
(
select
null as altitudeMode,
Coordinates as 'coordinates'
for xml path('Polygon'), type)
from Mapping for xml path('Placemark'), type))
for xml path ('Line') , type)
for xml path ('Doc'), root('kml'))
I want to save the output of the query as .XML file on to local drive.Please advise.
Not the most elegant way but it is possible to use bulk copy program
and xp_cmdshell
to do this. Few things first, xp_cmdshell
is blocked by default by SQL Server as part of the security configuration so you will need to enable that first and BCP
requires you to have access to the directory that you want to create the file.
To enable xp_cmdshell
you'll need run sp_configure
and RECONFIGURE
, use this:
EXEC sp_configure'xp_cmdshell', 1
RECONFIGURE
GO
EXEC sp_configure 'show advanced options', 1
RECONFIGURE
GO
Then you can run the following:
EXEC xp_cmdshell 'bcp "SELECT * FROM [Database].dbo.[Table] FOR XML AUTO,
ELEMENTS" queryout "C:\test.xml" -c -T'
Just add your query into it and make sure you add []
around your table names.
The Microsoft Documents for xp_cmdshell are here and bcp can be found here
Using bcp
is definite choice especially when working with large data sets. Alternatively, you can try using SQL Management Studio
- Export Data
.
Right Click
on database name, then Tasks
, then Export Data
The menu is opened. Click Next
Then choose SQL Server Native Client
, sql server, database name and authentication method:
Then where to save the data:
Then how we are getting the data (in your case SQL query):
Past the query:
Then we have some settings, click finish
.
To save the results of a remote query to a local file, you could use a Powershell script like this example:
$connection = New-Object System.Data.SqlClient.SqlConnection("Data Source=YourServer;Initial Catalog=YourDatabase;Integrated Security=SSPI")
$command = New-Object System.Data.SqlClient.SqlCommand(@("
select 'TEST.kml' as name,
(select 'TEST' as name, (
select (
select top 10 issue as name,
null as description,
null as 'Point/coordinates',
(
select
null as altitudeMode,
Coordinates as 'coordinates'
for xml path('Polygon'), type)
from Mapping for xml path('Placemark'), type))
for xml path ('Line') , type)
for xml path ('Doc'), root('kml');"), $connection);
$connection.Open();
$command.ExecuteScalar() | Out-File -FilePath "C:\KmlFiles\YourFile.kml";
$connection.Close();
The script can be executed from a command prompt by saving the script to a file with a ".ps1" extension and using a command like:
powershell -ExecutionPolicy RemoteSigned -File "C:\PowershellScripts\ExampleExport.ps1"
This command can be scheduled using a Windows Task Scheduler task to automate the export. Alternatively, schedule using a SQL Server agent job with a Powershell or CmdExec step.
