SQL XML 向根添加元素

问题描述

我有一个通过 SQL 生成的 XML，根如下所示:

I have an XML that is being generated via SQL and the root looks like this:

<ArrayOfKeyValueOfstringPunchListCellModel84zsBx89 
      ns1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">

我希望它看起来像这样:

I want it to look like so:

<ArrayOfKeyValueOfstringPunchListCellModel84zsBx89 
      xmlns:i="http://www.51sjk.com/Upload/Articles/1/0/342/342674_20230207091242144.jpg" 
      xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">

这是我的 SQL 代码:

Here is my SQL code:

DECLARE @persons XML = (
SELECT(
blah blah blah
)FOR XML PATH(''), ROOT('ArrayOfKeyValueOfstringPunchListCellModel84zsBx89'))
set @persons.modify('insert ( attribute ns1 {"http://schemas.microsoft.com/2003/10/Serialization/Arrays"}) into (/ArrayOfKeyValueOfstringPunchListCellModel84zsBx89)[1]')
    SELECT @persons

它返回第一个根，我如何让它像我展示的第二个根一样返回?

and it returns the first root, how do I get it return like the second root I showed?

推荐答案

您需要使用 WITH XMLNAMESPACES

试试这个:

WITH XMLNAMESPACES('http://www.51sjk.com/Upload/Articles/1/0/342/342674_20230207091242144.jpg' AS i
                  ,DEFAULT 'http://schemas.microsoft.com/2003/10/Serialization/Arrays')
SELECT NULL
FOR XML PATH('ArrayOfKeyValueOfstringPunchListCellModel84zsBx89')

结果

<ArrayOfKeyValueOfstringPunchListCellModel84zsBx89 xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:i="http://www.51sjk.com/Upload/Articles/1/0/342/342674_20230207091242144.jpg" />
