Update XML node value in SQL Server

Question

You can do something like this:

UPDATE 
   dbo.profiles
SET 
   ProfileXML.modify('replace value of (/ProblemProfile/GroupID/text())[1] with "0"')
WHERE
   id = 23

Check out this article on SQL Server 2005 XQuery and XML-DML for more details on what you can do with the .modify keyword (insert, delete, replace etc.).

PS: In order to get the value, it would be a lot easier to do just this:

SELECT ProfileXML.value('(/ProblemProfile/GroupID)[1]', 'int') as ID
FROM dbo.profiles
WHERE id = 23

(unless of course you need the XML as a SQL variable for something else later on)
