XML 同名但属性不同的多个节点 SQL

Question

我想返回 PackageUOM 为“EA”的维度。目前，我只获取第一个子节点，这会导致问题！

我知道我只想在 PackageUOM 是 EA 时提取尺寸，但我不知道该怎么做。任何帮助，将不胜感激。谢谢。

供参考，这是在 SQL 2014 中

您是否正在寻找类似以下的内容？

Declare @x xml = '<Packages>
        <Package MaintenanceType="A">
          <PackageUOM>PL</PackageUOM>
          <QuantityofEaches>50</QuantityofEaches>
          <Orderable>Y</Orderable>
          <Dimensions UOM="IN">
            <Height>40.7500</Height>
            <Width>42.0000</Width>
            <Length>48.0000</Length>
          </Dimensions>
        </Package>
        <Package MaintenanceType="A">
          <PackageUOM>EA</PackageUOM>
          <QuantityofEaches>1</QuantityofEaches>
          <Orderable>Y</Orderable>
          <Dimensions UOM="IN">
            <Height>7.2500</Height>
            <Width>17.0000</Width>
            <Length>10.2500</Length>
          </Dimensions>
          <Weights UOM="PG">
            <Weight>8.8400</Weight>
          </Weights>
        </Package>
      </Packages>'

select node.value('(Dimensions/Height/text())[1]', 'VARCHAR(20)') AS [Height],
       node.value('(Dimensions/Width/text())[1]', 'VARCHAR(20)') AS [Width],
       node.value('(Dimensions/Length/text())[1]', 'VARCHAR(20)') AS [Length]
from @x.nodes('/Packages/Package[PackageUOM/text() = "EA"]') AS nodes(node);

在此您将获得为PackageUOM = 'EA' 过滤的数据 并将该记录的维度设为 3 列

另外请注意，我使用了“VARCHAR(20)”而不是“DECIMAL(18,4)”，以避免由于任何非数字数据作为米左右的测量单位而崩溃。
