OPENXML将xml导入ms sql - namespace

标签： sql xml namespaces xquery sql-server-openxml

我使用这个网站很长一段时间，很多次它帮助我解决了各种问题。 这次我被困住了。我尝试将一个复杂的xml导入到ms-sql表中。

我尝试OPENXML和XQuery函数，但我在声明和使用命名空间（或命名空间）方面遇到了一些问题。我不熟悉这种复杂的xml和namespaceuri。我需要一个ideea来获取数据到表格。我已成功使用更简单的xml，即使有一个命名空间。我已经手动删除了前11行并且选择的波纹管非常精细......

＆＃13;
＆＃13; 
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
＆＃13;

首先发表一些评论

  • FROM OPENXML已过时，不应再使用（罕见例外退出）
  • 您的XML在此处<?xml version=''1.0'' encoding=''UTF-8''?>包含显式编码。这会迫使你走VARCHAR - 路径，这与不是普通的拉丁字符有关。最好用utf-16替换它，然后转到NVARCHAR - 路径。在这种情况下，您必须在XML文字前面设置“N”。
  • 你必须处理相当复杂的命名空间......难以阅读......如果你可以确定，没有重复的名称，你可以放弃命名空间声明并在前面放置一个*:每个元素。
  • 增加了一些额外的工作：内部S2SCTScf:FIToFICstmrCdtTrf定义了一个新的默认命名空间。我将其与innerDeflt混淆了。

这是变量声明

这是查询：首先声明命名空间。您的节点是1：1的纯结构，因此只需在元素名称后面添加元素名称XPath即可读取它们。只有<CdtTrfTxInf>出现两次需要1:n-approach APPLY和.nodes()。

在我的示例中，您可以获得XML中隐藏的任何类型数据的模板。其余的由你决定。

WITH XMLNAMESPACES(DEFAULT  'urn:S2SCTScf:xsd:$SCTScfBlkCredTrf'
                           ,'urn:S2SCTScf:xsd:$SCTScfBlkCredTrf' as S2SCTScf
                           ,'http://www.w3.org/2001/XMLSchema-instance' AS xsi
                           ,'urn:S2SCTScf:xsd:$SCTScfBlkCredTrf SCTScfBlkCredTrf.xsd' AS schemaLocation
                           ,'urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02' AS innerDeflt)
SELECT rt.value(N'(S2SCTScf:SndgInst)[1]','nvarchar(max)') AS SndgInst
      ,rt.value(N'(S2SCTScf:RcvgInst)[1]','nvarchar(max)') AS RcvgInst

      ,rt.value(N'(S2SCTScf:FIToFICstmrCdtTrf/innerDeflt:GrpHdr/innerDeflt:MsgId)[1]','nvarchar(max)') AS MsgId
      ,rt.value(N'(S2SCTScf:FIToFICstmrCdtTrf/innerDeflt:GrpHdr/innerDeflt:CreDtTm)[1]','datetime') AS CreDtTm
      --more like this
      ,rt.value(N'(S2SCTScf:FIToFICstmrCdtTrf/innerDeflt:GrpHdr/innerDeflt:TtlIntrBkSttlmAmt/@Ccy)[1]','nvarchar(max)') AS TtlIntrBkSttlmAmt_Ccy
      ,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
