OPENXML将xml导入ms sql – namespace

2023年5月12日 154次阅读

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.

<?xml version='1.0' encoding='UTF-8'?>

我尝试OPENXML和XQuery函数,但我在声明和使用命名空间(或namespaceuri)时遇到了一些问题.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,而选择的波纹管工作非常精细……

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

最佳答案首先是一些评论

> FROM OPENXML已过时,不应再使用(罕见的异常退出)
>您的XML在此处包含显式编码<？xml version =”1.0”coding =”UTF-8”？>.这会强制您使用VARCHAR路径,这与非普通拉丁字符的连接很危险.最好用utf-16替换它并转到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,你可以让命名空间声明离开并在每个元素前放置一个* :.
>什么增加了一些额外的努力：你的内部S2SCTScf：FIToFICstmrCdtTrf定义了一个新的默认命名空间.我把它与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,因此可以通过在形成XPath的元素名称后添加元素名称来简单地读取它们.只有< CdtTrfTxInf>出现两次,需要使用APPLY和.nodes()进行1：n方法.

在我的示例中,您将获得隐藏在XML中的任何类型数据的模板.剩下的由你决定.
