内部要素属性を取得するためのXquery

dbo.USR_YALE_IMODULES_EMAIL_WEBSERVICE_LOGという名前のテーブルのresponseというxml列に、次のxmlがあります。エラーとメッセージ要素の属性コードと説明を正しく取得できません。誰でも私が間違っていることを説明できますか？私は1727行のエラーがあり、それよりはるかに少ないです。私はおもしろいです内部要素属性を取得するためのXquery

select response.query('declare namespace Error="http://imodules.com/WebServices/EmailCategoryQuery/Error";/Error:EmailCategoryUpdateResults/EmailCategoryUpdateMemberResult/Error[@Code[1]]') as result 
FROM dbo.USR_YALE_IMODULES_EMAIL_WEBSERVICE_LOG

これはちょうど空白を返します。

ありがとうございます。

単純なクエリを実行するには、任意の名前空間の*記号を使用することができます。例えば、このクエリ戻りエラー要素：次にクエリがエラーコードを抽出する

;WITH XMLNAMESPACES('http://imodules.com/WebServices/EmailCategoryQuery/' AS q) 
    SELECT 
     response.query('/EmailCategoryUpdateResults/q:EmailCategoryUpdateMemberResult/q:Error') 
    FROM dbo.USR_YALE_IMODULES_EMAIL_WEBSERVICE_LOG

：明示的な名前空間で

SELECT 
     response.query('/*:EmailCategoryUpdateResults/*:EmailCategoryUpdateMemberResult/*:Error') 
    FROM dbo.USR_YALE_IMODULES_EMAIL_WEBSERVICE_LOG

次にクエリが同じ結果を与える

SELECT response.value('(/*:EmailCategoryUpdateResults/*:EmailCategoryUpdateMemberResult/*:Error/@Code)[1]', 'varchar(100)') 
    FROM dbo.USR_YALE_IMODULES_EMAIL_WEBSERVICE_LOG

こちらがお役に立てば幸いです。
