Update XML-Attribut in SQL Server mit Namensräumen

Question

Ich habe eine Tabelle mit XML-Spalte 'Data'. meine Anforderung ist, Attribute Uri und InstanceName zu ändern, wie wir den Code fördern. Ich schrieb unten Update Statements, um die Arbeit zu machen. Bei der Ausführung sehe ich 1 Zeile (n) betroffen, aber leider wird nichts aktualisiert. Jede Hilfe wird sehr geschätzt. Vielen Dank!.

Hier sind die Beispieldaten in der Datenspalte.

'<DataFeed xmlns="http://www.tech.com/datafeed/dfx/2010/04" xmlns:plugin="pluginExtensions" Type="TODO" Guid="TODO" UserAccount="DF_LEAN_PopulateCommentsSubForm" Locale="en-US" DateFormat="" ThousandSeparator="" NegativeSymbol="" DecimalSymbol="" SendingNotifications="false" SendJobStatusNotifications="false" RecipientUserIds="" RecipientGroupIds="" RecipientEmailAddresses="" Name="CI_C11.01_Lean-Lean_Reject Comments_A2A" >

Answer 1

Sie benötigen WITH XMLNAMESPACES in beiden Update-Anweisungen zu verwenden, und Sie müssen den Namespace
clr-namespace:ArcherTech.DataFeed.Activities.Transporters;assembly=ArcherTech.DataFeed
für den transporters:ArcherWebServiceTransportActivity Knoten verwenden.

WITH XMLNAMESPACES(DEFAULT 'http://www.tech.com/datafeed/dfx/2010/04', 
        'clr-namespace:ArcherTech.DataFeed.Activities.Transporters;assembly=ArcherTech.DataFeed' as t) 
UPDATE Test_TBD set 
Data.modify('replace value of (/DataFeed/Transporter/t:ArcherWebServiceTransportActivity/@Uri)[1] with "https://arcs-x"'); 

WITH XMLNAMESPACES(DEFAULT 'http://www.tech.com/datafeed/dfx/2010/04', 
        'clr-namespace:ArcherTech.DataFeed.Activities.Transporters;assembly=ArcherTech.DataFeed' as t) 
UPDATE Test_TBD set 
Data.modify('replace value of (/DataFeed/Transporter/t:ArcherWebServiceTransportActivity/@InstanceName)[1] with "ARCS-X"'); 

Answer 2

Nur für Vollständigkeit, wie Sie die Antwort WITH XMLNAMESPACES bereits gefunden haben, gibt es andere Ansätze als auch (aber zugegebenermaßen würde ich mit Mikaels Vorschlag gehen)

DECLARE @xml XML= 
'<DataFeed xmlns="http://www.tech.com/datafeed/dfx/2010/04" xmlns:plugin="pluginExtensions" Type="TODO" Guid="TODO" UserAccount="DF_LEAN_PopulateCommentsSubForm" Locale="en-US" DateFormat="" ThousandSeparator="" NegativeSymbol="" DecimalSymbol="" SendingNotifications="false" SendJobStatusNotifications="false" RecipientUserIds="" RecipientGroupIds="" RecipientEmailAddresses="" Name="CI_C11.01_Lean-Lean_Reject Comments_A2A" >

--The InstanceName changed
