使用SQL，我想将我的数据放入这些特定的列中：

CIM | Messgae | Classname | InstanceID | PropertyName |价值| DisplayValue

我很抱歉，因为这个问题非常类似于此处发布的问题： Parse XML file using SQL into Specific Columns

但是我被用户批评再次发布问题因为我稍微改变了我的XML文档。

帮助演示XML模式的图表：

Answer 1

试试这样：

SELECT @xml.value(N'(/CIM/@CIMVERSION)[1]',N'nvarchar(max)') AS CIM_version
      ,@xml.value(N'(/CIM/MESSAGE/@ID)[1]',N'nvarchar(max)') AS Message_Id

      ,vni.value(N'(INSTANCENAME/KEYBINDING/KEYVALUE/text())[1]',N'nvarchar(max)') AS Keybinding_Value

      ,vni.value(N'(INSTANCE/@CLASSNAME)[1]',N'nvarchar(max)') AS Instance_ClassName

      ,prp.value(N'@NAME',N'nvarchar(max)') AS Prop_Name
      ,prp.value(N'(VALUE/text())[1]',N'nvarchar(max)') AS Prop_Value
      ,prp.value(N'(DisplayValue/text())[1]',N'nvarchar(max)') AS Prop_DisplayValue
FROM @xml.nodes(N'/CIM/MESSAGE/SIMPLEREQ/VALUE.NAMEDINSTANCE') AS A(vni)
CROSS APPLY vni.nodes('INSTANCE/PROPERTY') AS B(prp);

某些值在xml中只有一次。我直接从您的@xml获取它们。作为第二级，您有重复元素<VALUE.NAMEDINSTANCE>和 - 嵌入 - 重复元素<PROPERTY>。

结果
