SQL Server Xml命名空间查询问题

xpath namespaces sql-server-2008 xml

CaffGeek · 技术社区 · 14 年前

我在xml变量中有以下内容 @ResultData

<EntityKey_x005B__x005D_>
  <EntityKey>
    <KeyData xmlns="http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKey">
      <KeyField>
        <Field>JournalNum</Field>
        <Value>LJRN000071</Value>
      </KeyField>
    </KeyData>
  </EntityKey>
  <EntityKey>
    <KeyData xmlns="http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKey">
      <KeyField>
        <Field>JournalNum</Field>
        <Value>LJRN000072</Value>
      </KeyField>
    </KeyData>
  </EntityKey>
  <EntityKey>
    <KeyData xmlns="http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKey">
      <KeyField>
        <Field>JournalNum</Field>
        <Value>LJRN000073</Value>
      </KeyField>
    </KeyData>
  </EntityKey>
  <EntityKey>
    <KeyData xmlns="http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKey">
      <KeyField>
        <Field>JournalNum</Field>
        <Value>LJRN000074</Value>
      </KeyField>
    </KeyData>
  </EntityKey>
</EntityKey_x005B__x005D_>

xmlns=... 在节点上。在.Net中,我可以做一些类似的事情 "{http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKey}KeyData" 要检索它,但我在SQL中得到一个语法错误。

SELECT  IDENTITY(int,1,1) as 'ID',
    c.query('(KeyData/KeyField/Value)[1]') as 'JournalNum'
INTO    #tmpBatches
FROM    @ResultData.nodes('//EntityKey') t(c)

思想?建议?解决?

明白了…当然,问了之后

    ;WITH XMLNAMESPACES (N'http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKey' as DYN)
    SELECT  IDENTITY(int,1,1)   
                as 'ID',
            c.value('(DYN:KeyData/DYN:KeyField/DYN:Value)[1]', 'VARCHAR(40)')
                as 'JournalNum'
    INTO    #tmpBatches
    FROM    @ResultData.nodes('//EntityKey') t(c)

 ;WITH XMLNAMESPACES (DEFAULT N'http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKey') 
        SELECT   IDENTITY(int,1,1)                                                
        as 'ID', c.value('(<strike>DYN:</strike>KeyData/DYN:KeyField/DYN:Value)[1]', 'VARCHAR(40)')
        as 'JournalNum'
            INTO #tmpBatches
        FROM @ResultData.nodes('//EntityKey') t(c)

另外,我偶然发现了一些注释,当存在多个名称空间并且您知道不会发生冲突时,如何忽略所有名称空间。 Someone's blog.
