What am I doing wrong with this XML query?

  I have a table (Messages) with XML stored as a varchar(max) column (Payload).

  The XML is formatted like this:

  <NCOAPACP xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="uri://www.gen.da.hob/VC/Contract/QualityManagement/EMSM">

  <VID>3656183</VID>

  </NCOAPACP>

  How do I query the table to get a list of all the values in the VID node? Every time I query using what I thought was the right way, I get a list of null values.

  Edit - sorry, I didn't post my actual query. I'm embarrassed as to where I ended up with it.

  You probably didn't use the namespace.

  DECLARE @x TABLE (Payload VARCHAR(max));

  INSERT @x (Payload)

  VALUES ('<NCOAPACP xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="uri://www.gen.da.hob/VC/Contract/QualityManagement/EMSM">

  <VID>3656183</VID>

  </NCOAPACP>');

  WITH XMLNAMESPACES (DEFAULT 'uri://www.gen.da.hob/VC/Contract/QualityManagement/EMSM')

  SELECT nd.value ('./text()[1]','int') AS vid

  FROM @x AS x

  CROSS APPLY ( -- Convert to XML

  SELECT cast(x.Payload AS XML)

  ) x2(PayloadXml)

  -- Get the VID nodes

  CROSS APPLY x2.PayloadXml.nodes('NCOAPACP/VID') c(nd)
