Question

I’d like to know if it is possible to add TAG PREFIX before every ELEMENT TAG
in the result of FOR XML AUTO mode.

I know it’s possible with RAW mode but I need to make its as hierarchy as possible xml result

Something like this:

       <prefix:attName>
        <prefix:ID>value</prefix:ID>
        <prefix:name>value</prefix:name>
      </prefix:attName>

and the query in the RAW mode will be like this:

SELECT ID, 
      Name,
FROM TableName 
FOR XML RAW ('prefix'), ROOT('prefix:attName'), ELEMENTS

Answer 1

You can achieve this using Aliases:

WITH XMLNAMESPACES ('prefix' AS prefix)
SELECT  ID AS [prefix:ID], 
        Name AS [prefix:Name]
FROM    TableName AS [prefix:attName]
FOR XML AUTO, ROOT('prefix:attName'), ELEMENTS
