Do you need to convert XML to varbinary?
Use the XML datatype. If wanting to use varbinary you’ll need to convert to retrieve and store the data, so I’d advice against that. You might as well use the proper datatype for data. Almost always – any possible resource or performance gain would be outweighed by difficulty of use and maintenance.
What does XML Path, type, and nvarchar do?
Please explain what does for xml path (”), TYPE) .value (‘.’, ‘NVARCHAR (MAX)’) do here . A common technique for aggregate string concatenation before SQL Server 2017 is using XML data type methods along with STUFF to remove the extra delimiter.
What does the XML data type method do?
The value XML data type method takes an XQuery expression with ‘.’ representing the current node (only node here) and the second argument being the desired SQL data type to be returned. Finally, the STUFF function removes the extraneous leading delimiter from the string.

Result (XML type):
How are XML files treated in SQL Server?
Neither SSIS nor Access has a native XML data type that is directly compatible and equivalent to the SQL Server’s XML data type. Therefore, to avoid the pipeline mangling of the XML document as it travels through, we will treat all input XML documents as varbinary (MAX) and all XML documents returned by SQL Server as nvarchar (MAX).
Can a XML file be shredded with XQuery?
The XML data can be shredded with XQuery later. The XML data can be indexed with a number of different XML index types, which help the XQuery shredding. As far as I can see, the only reason to use varbinary (max) over xml is if you expect to be putting more than 2GB of data into one field.
How is XML data compared to XML Schema collection?
The XML data can be compared to an XML Schema Collection, to give the functionality of typed XML. The XML data can be shredded with XQuery later. The XML data can be indexed with a number of different XML index types, which help the XQuery shredding.
