Sql XML显式分解和添加问题

因此，我目前编写了一些针对XML EXPLICIT的

SQL语句，除了我遇到的两件事之外，一切都很顺利

当我尝试添加这个额外的4标签层时，它只是在Chase部分的底部添加PatientData，而不是在每个Chase中添加

如下

<ChaseRequests dtGenerated="Friday, January 30, 2015 5:24:39 PM">
  <Chases>
    <Chase id="12345">
      <PracticeId><![CDATA[82791]]></PracticeId>
      <AccountId><![CDATA[8279101]]></AccountId>
      <RequestingCompany><![CDATA[DERP]]></RequestingCompany>
    </Chase>
    <Chase id="12346">
      <PracticeId><![CDATA[82791]]></PracticeId>
      <AccountId><![CDATA[8279101]]></AccountId>
      <RequestingCompany><![CDATA[DERP]]></RequestingCompany>
      <PatientData />
      <PatientData />
    </Chase>
  </Chases>
</ChaseRequests>

我的理想结果

<ChaseRequests dtGenerated="Friday, January 30, 2015 5:24:39 PM">
    <Vendor ID="Derp"/>
    <Request ID="Herp"/>
  <Chases>
    <Chase id="12345">
      <PracticeId><![CDATA[82791]]></PracticeId>
      <AccountId><![CDATA[8279101]]></AccountId>
      <RequestingCompany><![CDATA[DERP]]></RequestingCompany>
      <PatientData />
    </Chase>
    <Chase id="12346">
      <PracticeId><![CDATA[82791]]></PracticeId>
      <AccountId><![CDATA[8279101]]></AccountId>
      <RequestingCompany><![CDATA[DERP]]></RequestingCompany>
      <PatientData />
    </Chase>
  </Chases>
</ChaseRequests>



仅供参考-我计划在PatientData标记中放置更多嵌套标记-我只希望PatientData标记出现在每个“Chase”区域中

任何信息将不胜感激

按顺序处理行，因此必须对行施加与其层次关系相匹配的顺序。像这样：

SELECT
    tag,
    parent,
    [ChaseRequests!1!dtGenerated],
    [Chases!2!],
    [Chase!3!id],
    [Chase!3!PracticeId!CData],
    [Chase!3!AccountId!CData],
    [Chase!3!RequestingCompany!CData],
    [PatientData!4!Element]
FROM (SELECT 
    1 Tag,
    NULL Parent,
    'Friday, January 30, 2015 5:24:39 PM' as [ChaseRequests!1!dtGenerated],

注意：这只会变得更复杂，你越深入。你真的应该考虑切换到<代码>路径>代码>或者<代码> Auto <代码>，以使自己更容易。
谢谢输入！这肯定帮了我解决了筑巢的问题——不确定你是否能帮我解决我需要的“额外”两条线。如果我能保留我的CDATA标记，我肯定会使用XML路径：(
