私のXMLは次のようになります
<p:initiateTest xmlns:S52="https://collaborate.com/svn/edm/tdp/CharacteristicEnumerations"
xmlns:p="http://collaborate.com/svn/capabilities/tdp/ManageNetworkAndServiceDiagnosticsV4/"
xmlns:p1="http://wsi.nat.com/2005/06/StandardHeader/"
xmlns:p2="https://collaborate.com/svn/edm/tdp/Test"
xmlns:p3="https://collaborate.com/svn/edm/tdp/Parties"
xmlns:p4="https://collaborate.com/svn/edm/tdp/MORT" >
<p1:standardHeader>
<p1:stateCode>OK</p1:stateCode>
</p1:standardHeader>
</p:initiateTest>
以下のTSQLを実行すると、完了しますが、状態コード値が返されません
Declare @mxml XML
Select @mxml = xmlString
From CT_GTCS_Temp_XML
Where ID = 1
;WITH XMLNAMESPACES( 'p' AS p, 'p1' as p1, 'p2' AS p2)
select feed.xx.value('.','VARCHAR(MAX)') as statecode
from @mxml.nodes('//p:initiateTest/p1:standardHeader/p1:stateCode') feed(xx)
