Generated KML file from SQL query save to local drive
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', 1RECONFIGUREGOEXEC sp_configure 'show advanced options', 1RECONFIGUREGO
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
.
- Open the interface -
Right Click
on database name, thenTasks
, thenExport 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.
