Question

我使用Nodes方法将一些XML数据分解成一个表格，而我只缺少一个部分。我需要一个特定的XML元素，但它备份（原谅我糟糕的语法，处理XML的新东西）来自我粉碎的XML。我已发布，我希望所有相关代码：

XML：

<ToDoList xmlns="----.----.MappingObjects/XmlSchemas/ToDoList.xsd">
  <Step>
    <StepId>f3ab5132-fcf4-47c4-929f-ab7464d3bcc7</StepId>
    <Rank>1</Rank>
    <IsComplete>true</IsComplete>
    <CompletionDate>2017-04-17T17:12:45Z</CompletionDate>
    <CompletionUser>Michael Johnson</CompletionUser>
    <Text></Text>
    <CalibrationId>3</CalibrationId>
    <CalibrationValues>
      <Value>
        <Standard>1111</Standard>
        <UnitOfMeasureName>NewU</UnitOfMeasureName>
        <Min>1111</Min>
        <Normal>1112</Normal>
        <Max>1113</Max>
        <BeforeReading>1111</BeforeReading>
        <AfterReading>1112</AfterReading>
        <DateCalibrated>2017-04-17T17:12:00Z</DateCalibrated>
        <FailBefore>false</FailBefore>
        <FailAfter>false</FailAfter>
      </Value>
      <Value>
        <Standard>245.000</Standard>
        <UnitOfMeasureName>NewU</UnitOfMeasureName>
        <Min>245</Min>
        <Normal>250</Normal>
        <Max>280</Max>
        <BeforeReading>245</BeforeReading>
        <AfterReading>250</AfterReading>
        <DateCalibrated>2017-04-17T17:12:00Z</DateCalibrated>
        <FailBefore>false</FailBefore>
        <FailAfter>false</FailAfter>
      </Value>
    </CalibrationValues>
  </Step>
</ToDoList>

SQL：

;with XMLNAMESPACES('----.-----.MappingObjects/XmlSchemas/ToDoList.xsd' as NS)

select WOId,
       N.Step.value('(NS:Standard)[1]', 'nvarchar(max)') as [Standard],
       N.Step.value('(NS:UnitOfMeasureName)[1]','nvarchar(32)') as [UOM],
       N.Step.value('(NS:Min)[1]','float') as [Min],
       N.Step.value('(NS:Normal)[1]','float') as Normal,
       N.Step.value('(NS:Max)[1]','float') as [Max],
       N.Step.value('(NS:BeforeReading)[1]','float') as BeforeReading,
       N.Step.value('(NS:AfterReading)[1]','float') as AfterReading,
       dbo.fn_clr_GetCustomerLocalTimeFromUTC(@CUSTOMERTIMEZONE, N.Step.value('(NS:DateCalibrated)[1]','datetime')) as DateCalibrated,
       N.Step.value('(NS:FailBefore)[1]','bit') as FailBefore,
       N.Step.value('(NS:FailAfter)[1]','bit') as FailAfter


from tblWorkOrderToDoList WOTD
cross apply Data.nodes('//NS:Value') N(Step)

现有表返回以下列（为简洁起见缩写）：

WOId Standard UOM Min Normal Max BeforeReading AfterReading DateCalibrated

我想看到的内容：

WOId CalibrationId Standard UOM Min Normal Max BeforeReading AfterReading

其中每个返回行的CalibrationId（使用上面的XML）3。

您可以将XML分为两次，首先是Step元素级别，然后是Value，这样您就可以从这两个元素中获取必要的信息：

select 
    WOId,
    T.Step.value('NS:CalibrationId[1]','int') as CalibrationId
    N.Value.value('NS:Standard[1]', 'nvarchar(max)') as [Standard],
    N.Value.value('NS:UnitOfMeasureName[1]','nvarchar(32)') as [UOM],
    N.Value.value('NS:Min[1]','float') as [Min],
    ....
from tblWorkOrderToDoList WOTD
cross apply WOTD.Data.nodes('//NS:Step') T(Step)
cross apply T.Step.nodes('NS:CalibrationValues/NS:Value') N(Value)

使用节点移回XML
