The problem is that the XML nodes with the Value attribute are not directly accessible because of namespaces. To solve this issue, you can use the XSLT function to extract the values from the XML nodes. Here’s an updated query that should give you all the values for each Value node: DECLARE @fpid INT = 142; DECLARE @fid INT = 5; SELECT fpid, fid, name, CAST(ExtendedStatement.value('(./text())[1]', 'nvarchar(max)') as xml) as ESXML, x.
