我使用这个网站很长时间了，很多次它帮助我解决了各种问题。这次我卡住了。我尝试将像下面这样的复杂 xml 导入 ms-sql 表。

我尝试了 OPENXML 和 XQuery 函数，但在声明和使用命名空间（或命名空间uri）时遇到了一些问题。我不熟悉如此复杂的 xml 和 namespaceuri。我需要一个想法来将下面的数据放到表格中。即使使用一个命名空间，我也成功使用了更简单的 xml。我已经手动删除了前 11 行，并且选择波纹管工作得很好......

DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX)
SELECT @XML = XMLData FROM XMLwithOpenXML where id=6 --this is the xml without first 11 lines
EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML
SELECT * FROM OPENXML(@hDoc, 'FIToFICstmrCdtTrf/CdtTrfTxInf')
  WITH 
  (
    CCY [varchar](100) 'IntrBkSttlmAmt/@Ccy',
    IntrBkSttlmAmt [varchar](100) 'IntrBkSttlmAmt',
    TxId [varchar](100) 'PmtId/TxId',
    EndToEndId [varchar](100) 'PmtId/EndToEndId',
    ChrgBr [varchar](100) 'ChrgBr'
    --etc
  )
EXEC sp_xml_removedocument @hDoc
GO

先说几点

  • FROM OPENXML已过时，不应再使用（罕见异常退出）
  • 您的 XML 在此处包含显式编码<?xml version=''1.0'' encoding=''UTF-8''?>。这会迫使您走VARCHAR-path，这对于非纯拉丁字符的连接是危险的。最好用-path替换utf-16它。NVARCHAR在这种情况下，您必须在 XML 文字前设置一个“N”。
  • 您必须处理相当复杂的命名空间...难以阅读...如果您可以确定没有重复的名称，您可以放弃命名空间声明并将 a*:放在每个元素的前面。
  • 什么增加了一些额外的努力：您的内部S2SCTScf:FIToFICstmrCdtTrf定义了一个新的默认命名空间。我用innerDeflt.

这是变量声明

这就是查询：首先声明命名空间。您的节点是纯 1:1 结构的，因此只需在元素名称后添加元素名称即可读取它们，形成XPath. 只<CdtTrfTxInf>出现两次，需要一个1:n-approachwithAPPLY和.nodes()。

在我的示例中，您将获得一个模板，用于隐藏在 XML 中的任何类型的数据。剩下的就看你了。

WITH XMLNAMESPACES(DEFAULT  'urn:S2SCTScf:xsd:$SCTScfBlkCredTrf'
                           ,'urn:S2SCTScf:xsd:$SCTScfBlkCredTrf' as S2SCTScf

      ,rt.value(N'(S2SCTScf:FIToFICstmrCdtTrf/innerDeflt:GrpHdr/innerDeflt:TtlIntrBkSttlmAmt)[1]','int') AS TtlIntrBkSttlmAmt
      --all nodes are 1:1, just "more of the same"
      --But CdtTrfTxInf is there twice, therefore the call to OUTER APPLY rt.nodes()
      ,cti.value(N'(innerDeflt:PmtId/innerDeflt:EndToEndId)[1]','nvarchar(max)') AS EndToEndId
      --all the rest is following the same schema...
FROM @xml.nodes(N'S2SCTScf:SCTScfBlkCredTrf') AS A(rt) --root
OUTER APPLY rt.nodes(N'S2SCTScf:FIToFICstmrCdtTrf/innerDeflt:CdtTrfTxInf') AS B(cti) --CdtTrfTxInf
