TSQL - 查询XML和合并根节点

我试图建立在以下格式的XML（我们的供应商有没有XSD）：TSQL - 查询XML和合并根节点

<Submission> 
<Office Account="ACCOUNT"> 
    <schedule submissionPeriod="" areaOfLaw="" scheduleNum="abc"> 
     <outcome matterType="A:B"> 
      <outcomeItem Name="CASE_START_DATE">DATA</outcomeItem> 
      <outcomeItem Name="CASE_ID">DATA</outcomeItem> 
     </outcome> 
     <outcome matterType="C:D"> 
      <outcomeItem Name="CASE_START_DATE">DATA</outcomeItem> 
      <outcomeItem Name="CASE_ID">DATA</outcomeItem> 
     </outcome> 
    </schedule> 
    <schedule submissionPeriod="" areaOfLaw="" scheduleNum="def"> 
     <outcome matterType="E:F"> 
      <outcomeItem Name="CASE_START_DATE">DATA</outcomeItem> 
      <outcomeItem Name="CASE_ID">DATA</outcomeItem> 
     </outcome> 
    </schedule> 
</Office> 
<Office Account="ACCOUNT2"> 
    <schedule submissionPeriod="" areaOfLaw="" scheduleNum="ghi"> 
     <outcome matterType="A:B"> 
      <outcomeItem Name="CASE_START_DATE">DATA</outcomeItem> 
      <outcomeItem Name="CASE_ID">DATA</outcomeItem> 
     </outcome> 
    </schedule> 
</Office>

我有以下SQL

SELECT supplier_no AS 'Office/@Account' , 
    UPPER(LEFT(DATENAME(MM, GETDATE()), 3)) + '-' + DATENAME(YYYY, 
                  GETDATE()) AS 'Office/schedule/@submissionPeriod' , 
    'LEGAL HELP' AS 'Office/schedule/@areaOfLaw' , 
    supplier_no + '/CIVIL' AS 'Office/schedule/@scheduleNum' , 
    ClaimsTable.mattype1_code + ':' + ClaimsTable.mattype2_code AS 'Office/schedule/outcome/@matterType' , 
    (SELECT * FROM ( 

        SELECT 'CASE_START_DATE' AS 'outcomeItem/@Name', 'DATA' AS 'outcomeItem' UNION ALL 
        SELECT 'CASE_ID' AS 'outcomeItem/@Name', 'DATA' AS 'outcomeItem' 

       ) OutcomeItems FOR XML PATH(''), TYPE) AS 'Office/schedule/outcome' 

FROM ContractsTable 
    LEFT OUTER JOIN ClaimsTable ON ContractsTable.contract_no = ClaimsTable.contract_no 
WHERE ClaimsTable.compno = 2 
    AND ClaimsTable.submitted_period = 0 
FOR  XML PATH('Submission') , 
     TYPE

这是产生下面的XML

<Submission> 
    <Office Account="MHESUPPLIE"> 
<schedule submissionPeriod="FEB-2013" areaOfLaw="LEGAL HELP" scheduleNum="MHESUPPLIE/CIVIL"> 
    <outcome matterType="MHNS:MOUT"> 
    <outcomeItem Name="CASE_START_DATE">13/02/2013</outcomeItem> 
    <outcomeItem Name="CASE_ID">001</outcomeItem> 
    </outcome> 
</schedule> 
    </Office> 
</Submission> 
<Submission> 
    <Office Account="MHESUPPLIE"> 
<schedule submissionPeriod="FEB-2013" areaOfLaw="LEGAL HELP" scheduleNum="MHESUPPLIE/CIVIL"> 
    <outcome matterType="MHAS:MGUA"> 
    <outcomeItem Name="CASE_START_DATE">14/02/2013</outcomeItem> 
    <outcomeItem Name="CASE_ID">001</outcomeItem> 
    </outcome> 
</schedule> 
    </Office> 
</Submission>

显然，输出XML有多个根节点是无效。我试图找到一种方法将结果组合在一起以实现我需要的XML类型。有没有关于SQL Server 2005+如何实现的想法？

如果使用FOR XML PATH（''），ROOT（'Submission'）'会发生什么？ – 2013-02-14 16:30:06

我简化了你的查询。假设你的查询看起来是这样的：

SELECT STR(X) AS [office/schedule] 
FROM (VALUES(1),(2)) AS CompleQuery(x) 
FOR XML PATH('Submission'),TYPE;

产生：

<Submission><office><schedule> 1</schedule></office></Submission><Submission><office><schedule> 2</schedule></office></Submission>

为了得到这两个办公室标签为一个提交用这个代替：

SELECT (
SELECT STR(X) AS [office/schedule] 
FROM (VALUES(1),(2)) AS CompleQuery(x) 
FOR XML PATH(''),TYPE 
) 
FOR XML PATH('Submission'),TYPE;

因此，在改变PATH('Submission')到PATH('')您的查询，然后将其包裹到另一个SELECT ... FOR XML PATH('Submission'),TYPE;

结果：

<Submission><office><schedule> 1</schedule></office><office><schedule> 2</schedule></office></Submission>
