问题描述

我卡在 SQL 中 - 有人可以帮忙吗？

我有一个 XML 如下所示； 我想阅读 XML 标签并在 SQL 服务器中创建一个表。

我尝试了下面显示的查询，但没有获取数据。 结果集为空。 我使用了交叉应用并转换为 xml。

显然我可以将 XPath 查询写入 select 标记到列中，这就是我想要的，除了有 1000 个可能的标记名称，我不想把它们全部写出来（可能错过一个），因此我正在寻找我们读取 xml 标签并生成带有 SQL 中的值和标签的表的解决方案。

SELECT 
    t.ID,
    T0.Color.value('local-name(.)', 'nvarchar(max)') AS TagName,
    T0.Color.value('(@name)[1]','nvarchar(max)') AS EntityName,
    T0.Color.value('text()[1]','nvarchar(max)') AS TagValue  
FROM
    ConfigurationDnaItem t
CROSS APPLY 
    (SELECT 
         CAST(t.Value AS XML)) AS A(AllNodes)
CROSS APPLY 
    A.AllNodes.nodes('/hierarchy/nodes/list-entity') AS T0(Color)
WHERE 
    id = '1D09BFCB-AE0A-4346-835D-4BBCF2BBB503'

Output 需要

请参阅上面的表格结构，我正在寻找从选择 N/A 中删除会更好的最后一行。

感谢帮助。

目前还不清楚您期望的 output 是什么，但看起来您想要这样的东西

WITH XMLNAMESPACES(DEFAULT 'urn:guru.cincom.com-Hierarchy')
SELECT t.ID
      ,T0.Color.value('(extended-properties/extended-property[@name = "ALTNAME"]/text())[1]', 'nvarchar(max)') AS TagName
      ,T0.Color.value('@name','nvarchar(max)') AS EntityName
      ,T0.Color.value('(values/value/key-value/text())[1]','nvarchar(max)') AS TagValue  
FROM ConfigurationDnaItem t
CROSS APPLY (SELECT CAST(t.Value AS XML)) As A(AllNodes)
CROSS APPLY A.AllNodes.nodes('/hierarchy/nodes/list-entity[not(values/value/key-value/text() = "N/A")]') AS T0(Color)
where t.id = '1D09BFCB-AE0A-4346-835D-4BBCF2BBB503';

您现有的查询存在许多问题：

  • 您缺少命名空间声明。
  • local-name(.)将为您提供节点名称list-entity ，尚不清楚您为什么想要它。
  • 您似乎想要的一些数据存储在您需要按属性name过滤的extended-properties/extended-property中，然后提取内部文本。
  • @name为您获取name属性，该属性不存在于您的图像中。 然而，我把它留在了里面。 它不需要[1] 。
  • text()[1]不会得到任何东西，因为上下文节点没有任何直接的内部文本节点。 相反，您似乎想下降到values/value/key-value/text() 。
  • 要过滤掉N/A值，您需要以下谓词[not(values/value/key-value/text() = "N/A")]
