How to save SQL query result to XML file on disk

I would like to export table from SQL Server 2012 to XML file. I have found nice answer and here how to make XML result from SQL Server database query, but still I am missing how to save this result physically into file.

SQL query is:

SELECT [Created], [Text]
FROM [db304].[dbo].[SearchHistory]
FOR XML PATH('Record'), ROOT('SearchHistory')

I use Microsoft SQL Server Management Studio to execute this result. I see the XML in a result window, but I cannot save it.

There is "Save Result As.." in context menu, but with 98900 rows I run out of my 8GB memory with this option.

Is there a way how to save this query directly to the XML file on disk?

This example works for me for result sets up to 2GB in size.

EXEC master.dbo.sp_configure 'show advanced options', 1
RECONFIGURE
EXEC master.dbo.sp_configure 'xp_cmdshell', 1
RECONFIGURE

DROP TABLE IF EXISTS ##AuditLogTempTable

SELECT A.MyXML
INTO ##AuditLogTempTable
FROM
(SELECT CONVERT(nvarchar(max), 
    (
            SELECT
                A.*
            FROM
                [dbo].[AuditLog] A
                JOIN ImportProviderProcesses IPP ON IPP.ImportType = 'Z' 
                  AND A.OperatorID = IPP.OperatorID 
                  AND A.AuditTypeID in ( '400','424','425' )
            WHERE
                A.[PostTime] >= IPP.StartTime
                AND A.[PostTime] <= dateadd(second, 90, IPP.StartTime) 
                FOR XML PATH('Record'), ROOT('AuditLog')
        )
    , 0
    )   AS MyXML
) A

EXEC xp_cmdshell 'bcp "SELECT MyXML FROM ##AuditLogTempTable" queryout "D:\bcptest1.xml" -T -c -t,'

To this job in SQL Server 2012 is a pain in ass. Finally I end up to update it to SQL Server 2014 as there is already support for SQL UTF-8 files in sqlcmd.

  1. Create an SQL query and save it to the file.

  2. run following:

    sqlcmd -S -U sa -P sapassword -i inputquery_file_name -C65001 -o outputfile_name

You can also your SQL Server's extended stored procedures to export it to an xml file.

But you would need to configure the sql server before you can use it. 

EXEC master.dbo.sp_configure 'show advanced options', 1
RECONFIGURE
EXEC master.dbo.sp_configure 'xp_cmdshell', 1
RECONFIGURE

Once xp_cmdshel is enabled in the SQL Server. You can use the following command to export the data to an xml file. 

EXEC xp_cmdshell 'bcp "SELECT [Created], [Text] FROM [db304].[dbo].[SearchHistory] FOR XML PATH(''Record''), ROOT(''SearchHistory'')" queryout "C:\bcptest.xml" -T -c -t,'

You can always use the "Results to File" option in SSMS:

enter image description here

That should output the results of the query execution directly into a file on disk
