Select 所有 XML 节点并生成 SQL 服务器 table

Question

我卡在了 SQL - 谁能帮忙吗？

我有一个 XML 如下所示；我想读取 XML 标签并在 SQL 服务器中创建一个 table。

我尝试了如下所示的查询，但没有获取数据。结果集为空。我已经使用交叉应用并转换为 xml.

显然我可以将对 select 标签的 XPath 查询写入列中，这就是我想要的，除了有大约 1000 个可能的标签名称，我不想把它们全部写出来（并且可能错过了一个），因此我正在寻找我们读取 xml 标签并生成 table 的解决方案，其中的值和标签位于 SQL.

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 Required

请看上面的 table 结构我要从 selection N/A 中删除最后一行会好得多。

感谢您的帮助。

Answer 1

不太清楚您的预期输出是什么，但看起来您想要这样的结果

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';

您现有的查询存在一些问题：

您缺少命名空间声明。
local-name(.) 会为您提供节点名称 list-entity，目前尚不清楚您为什么想要它。
你似乎想要的一些数据存储在extended-properties/extended-property中，你需要通过属性name过滤，然后拉出内部文本。
@name 为您提供 name 属性，该属性不存在于您的图像中。但是我已经把它留在里面了。它不需要 [1].
text()[1] 不会给你任何东西，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，需要如下谓词[not(values/value/key-value/text() = "N/A")]
