Question

我正在尝试加载XML文档（下面是我如何接收文件的示例。我可以读取xml，但我无法将数据插入表中。任何帮助都会很感激。

<xml xmlns:dt="urn:dt" xmlns:msxsl="urn:schemas-microsoft-com:xslt" dateofservice="1/1/2016 10:00" mmsid="201599999999" userid="dxxxxx9-xxx0-xxdb-xxx0-e8xxxxxxbcd" npid="dfxxxxx9-6xx0-xxxx-bxx0-exxxc1xxxxxd" surveyid="xxxxxxx-xxxa-exxx-8xxx-xxxx56xxxxefb" memberid="sqlsrfr">

鉴于您设法将XML读入变量，完整（非规范化）查询是这样的：

您必须为MetaData，ResponseData和EventData设计三个表，并在那里插入数据。

如果您需要创建一种ID，请查看ROW_NUMBER() OVER()

btw：未使用声明的命名空间...并自己定义拟合数据类型（我只使用varchar(max)或int）。

WITH XMLNAMESPACES('urn:dt' AS dt
                  ,'urn:schemas-microsoft-com:xslt' AS msxsl)
,MetaData AS
(
    SELECT @xml.value('/xml[1]/@dateofservice','varchar(max)') AS md_DateOfService
          ,@xml.value('/xml[1]/@mmsid','varchar(max)') AS md_MmsID
          ,@xml.value('/xml[1]/@userid','varchar(max)') AS md_UserID
          ,@xml.value('/xml[1]/@npid','varchar(max)') AS md_NpID
          ,@xml.value('/xml[1]/@surveyid','varchar(max)') AS md_SurveyID
          ,@xml.value('/xml[1]/@memberid','varchar(max)') AS md_MemberID
          ,@xml.query('.') AS XMLNode
)
SELECT md.md_DateOfService
      ,md.md_MmsID
      ,md.md_UserID
      ,md.md_NpID
      ,md.md_SurveyID
      ,md.md_MemberID
      ,response.value('@qid','int') AS resp_qID
      ,response.value('@debug','int') AS resp_Debug
      ,response.value('@value','varchar(max)') AS resp_Value
      ,response.value('@element','varchar(max)') AS resp_Element
      ,response.value('@row','int') AS resp_Row
      ,response.value('@mapfield','varchar(max)') AS resp_MapField
      ,response.value('@type','varchar(max)') AS resp_Type
      ,response.value('@aid','int') AS resp_aID
      ,response.value('@placeholder','varchar(max)') AS resp_Placeholder
      ,response.value('@customtype','varchar(max)') AS resp_CustomType
      ,EventRow.value('@name','varchar(max)') AS evnt_Name
      ,EventRow.value('@time','varchar(max)') AS evnt_Time
      ,EventRow.value('@count','int') AS evnt_Count
      ,EventRow.value('@last','varchar(max)') AS evnt_Last
FROM MetaData AS md
CROSS APPLY md.XMLNode.nodes('/xml/response') AS One(response) 
CROSS APPLY md.XMLNode.nodes('/xml/surveyevents/event') AS The(EventRow)

使用OpenRow加载SQL XML
