Xquery, um inneres Elementattribut abzurufen

Ich habe das folgende XML in einer XML-Spalte namens response in einer Tabelle namens dbo.USR_YALE_IMODULES_EMAIL_WEBSERVICE_LOG. Ich habe Probleme, die Attribute Code und Beschreibung für Fehler- und Nachrichtenelemente korrekt abzurufen. Kann mir bitte jemand erklären was ich falsch mache? Ich bekomme 1727 Zeilen Fehler und es gibt viel weniger. Ich spielte mitXquery, um inneres Elementattribut abzurufen

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

dies liefert nur Blanks obwohl.

Vielen Dank im Voraus.

Abfrage einfacher zu tun, Sie * Symbol für beliebigen Namespace verwenden können. Zum Beispiel dieser Abfrage Rückkehr Fehler Elemente:

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

nächste Abfrage mit expliziter Namespace wird das gleiche Ergebnis:

;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

nächste Abfrage extrahieren Fehlercodes:

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

Ich hoffe, das hilft.
