SQL to XML无法创建正确的XMLNAMESPACE，因为有引号（我想）

我有以下疑问：

WITH XMLNAMESPACES ('CommonImport StudentRecordCount="1" 
xsi:schemaLocation="http://collegeboard.org/CommonImport CommonImport.xsd" 
xmlns="http://collegeboard.org/CommonImport" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"' AS CommonImport)
SELECT B.award_year_token AS [StudentID/AwardYearToken]
  ,A.student_ssn AS [StudentID/SSN]
  ,A.last_name AS [StudentName/LastName]
  ,A.first_name AS [StudentName/FirstName]
  ,A.alternate_id AS [StudentName/AlternateID]
  ,'2807' AS [CustomStrings/CustomString/FieldID]
  ,C.processed_status AS [CustomStrings/CustomString/Value]
  ,'2506' AS [CustomDates/CustomDate/FieldID]
  ,CAST (C.date_processed AS DATE) AS [CustomDates/CustomDate/Value]
FROM [dbo].[student] A INNER JOIN [stu_award_year] B ON A.[student_token] = B.[student_token]
LEFT OUTER JOIN [dbo].[isir_convert_data] C ON A.[student_ssn] = C.[ssn] AND B.award_year_token = C.award_year_token
--LEFT OUTER JOIN [user_string] E ON B.[stu_award_year_token] = E.[stu_award_year_token]
--WHERE B.AWARD_YEAR_TOKEN = 2018  --For 18-19 year.
WHERE B.AWARD_YEAR_TOKEN = 2017  --For 17-18 year.
  AND C.processed_status ='B'
  AND C.date_processed = (SELECT MAX (X.date_processed)
               FROM isir_convert_data X 
               WHERE C.ssn = X.ssn)
FOR XML PATH('Student'), ROOT('CommonImport')

由于引号处理不当，输出无法使用。如下所示：

<CommonImport xmlns:CommonImport="CommonImport StudentRecordCount=&quot;1&quot; xsi:schemaLocation=&quot;http://collegeboard.org/CommonImport CommonImport.xsd&quot; xmlns=&quot;http://collegeboard.org/CommonImport&quot; xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot;">

我是通过SQL Server生成的。您能就如何正确创建XML标记提供一些建议吗？如果我没有正确使用XMLNAMESPACE函数，请告诉我。感谢您的考虑。

您必须区分

名称空间的声明和 名称空间的使用 在我看来，StudentRecordCount应该是节点中的一个属性，与schemaLocation相同。第二个属性位于xmlns:xsi名称空间中

您没有说明预期的输出，但我的魔法水晶球告诉我，您可能需要：

WITH XMLNAMESPACES (DEFAULT 'http://collegeboard.org/CommonImport'
                  ,'http://www.w3.org/2001/XMLSchema-instance' AS xsi)
SELECT 1 AS [@StudentRecordCount]
      ,'http://collegeboard.org/CommonImport CommonImport.xsd' AS [@xsi:schemaLocation]
      ,'SomeOtherData' AS [Student/SomeElement]
FOR XML PATH('CommonImport');

结果

<CommonImport xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
              xmlns="http://collegeboard.org/CommonImport" 
              StudentRecordCount="1" 
              xsi:schemaLocation="http://collegeboard.org/CommonImport CommonImport.xsd">
  <Student>
    <SomeElement>SomeOtherData</SomeElement>
  </Student>
</CommonImport>

更新2 难看的变通办法

WITH cte AS
(
    SELECT object_id,name FROM sys.objects
)
SELECT 
CAST(REPLACE(REPLACE(REPLACE(CAST(
(
    SELECT COUNT(*) AS [@RecordCount]
          ,'http://collegeboard.org/CommonImport CommonImport.xsd' AS [@xsi_schemaLocation] --<-- "xsi:" is replaced with "xsi_"
          ,'http://collegeboard.org/CommonImport' AS [@_xmlns_] --<-- "xmlns" is not allowed
          ,'http://www.w3.org/2001/XMLSchema-instance' AS [@_xmlns_xsi] --<-- Same with "xmlns:xsi"
          ,(
            SELECT *
            FROM cte
            FOR XML PATH('Object'),TYPE
           )
    FROM cte
    FOR XML PATH('CommonImport'),TYPE) AS nvarchar(MAX)),'xsi_','xsi:'),'_xmlns_',' xmlns'),'xmlnsxsi','xmlns:xsi') AS XML);

或者，您可以创建完全没有名称空间的整个内容，并在末尾添加带有字符串方法的名称空间声明。

感谢@Shnugo的帮助。我想要的输出如下：我所有的文件都需要这个标签。我需要我的输出计数来填充StudentRecordCount，其中包含我在select语句中提取的记录数。@chrissimons属性的顺序在语义上并不重要。因此，我上面的代码似乎正是您所需要的。尝试调整您现有的代码，并返回更具体的问题。请尽量提供一个样本数据减少，但完整的MCVE。先生，祝福你！谢谢你的帮助！成功了！天哪，先生！你对我的帮助比你所知道的还要多！再次感谢你！
