使用名称空间更新SQL Server中的XML属性

我有一个包含xml列“Data”的表。我的要求是在升级代码时更改属性Uri和InstanceName。我写了下面的更新声明来完成这项工作。当我执行时，我看到1行受影响，但不幸的是，它没有更新任何内容。我们将非常感谢您的帮助。谢谢

CREATE TABLE [dbo].[Test_TBD](
    [Id] [int] NULL,
    [Data] [xml] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

GO   

 WITH XMLNAMESPACES(DEFAULT 'http://www.tech.com/datafeed/dfx/2010/04')
 UPDATE Test_TBD set
Data.modify('replace value of (/DataFeed/Transporter/ArcherWebServiceTransportActivity/@Uri)[1] with "https://arcs-x"');

 UPDATE Test_TBD set
 Data.modify('replace value of (/DataFeed/Transporter/ArcherWebServiceTransportActivity/@InstanceName)[1] with "ARCS-X"');

下面是数据列中的示例数据

您需要在更新语句中使用

和XMLNAMESPACES

，并且需要使用命名空间

clr名称空间：archetech.DataFeed.Activities.Transporters；assembly=archetech.DataFeed

对于

传输程序：ArcherWebServiceTransportActivity

节点

使用XMLNAMESPACES的

（默认值'http://www.tech.com/datafeed/dfx/2010/04',
'clr命名空间：ArcherTech.DataFeed.Activities.Transporters；assembly=ArcherTech.DataFeed'as t）
更新测试TBD集
Data.modify（（/DataFeed/Transporter/t:ArcherWebServiceTransportActivity/@Uri）[1]的值替换为“https://arcs-x"');

Data.modify（（/DataFeed/Transporter/t:ArcherWebServiceTransportActivity/@InstanceName）[1]的值替换为“ARCS-X”）；

只是为了完整性，正如您已经找到了XMLNAMESPACES的答案一样，还有其他方法（但无可否认，我同意Mikaels的建议）

我已将/DataFeed/Transporter/ArcherWebServiceTransportActivity/@Uri替换为/DataFeed/Transporter/*/@Uri，只是为了通过选择“全部”来验证它是否正常工作。它可能在这种情况下工作，但我希望选择所需的节点并进行更新。请说明我遗漏了什么。谢谢，我很高兴
