TSQL для группировки путей XML

Question

У меня возникают проблемы с попыткой группировать/вставлять результаты, как показано ниже.

Любая помощь была бы принята с благодарностью.

выход XML Обязательный

<WorkflowLog> 
    <Process id="Type1"> 
    <ProcessInstance id="M11111"> 
     <AuditTrailEntry> 
     <Data> 
      <Attribute name="TypeSubCause">EMB</Attribute> 
     </Data> 
     <WorkflowModelElement>C_Created</WorkflowModelElement> 
     <EventType>Start</EventType> 
     <TimeStamp>2013-10-02T10:00:33</TimeStamp> 
     <Originator>C_Team</Originator> 
     </AuditTrailEntry> 
     <AuditTrailEntry> 
     <Data> 
      <Attribute name="TypeSubCause">EMB</Attribute> 
     </Data> 
     <WorkflowModelElement>ITPSPotential</WorkflowModelElement> 
     <EventType>Start</EventType> 
     <TimeStamp>2013-10-03T09:15:32+10.00</TimeStamp> 
     <Originator>R_Team</Originator> 
     </AuditTrailEntry> 
    </ProcessInstance> 
    </Process> 
</WorkflowLog> 

Фактический выход XML из моего SQL процесса Id и ProcessInstance ID показываются несколько раз для

<WorkflowLog> 
    <Process id="Type1"> 
    <ProcessInstance id="M11111"> 
     <AuditTrailEntry> 
     <Data> 
      <Attribute name="TypeSubCause">EMBt</Attribute> 
     </Data> 
     <WorkflowModelElement>c_Created</WorkflowModelElement> 
     <EventType>Start</EventType> 
     <TimeStamp>2013-10-02T10:00:33+10.00</TimeStamp> 
     <Originator>C_Team</Originator> 
     </AuditTrailEntry> 
    </ProcessInstance> 
    </Process> 
    <Process id="Type1"> 
    <ProcessInstance id="M11111"> 
     <AuditTrailEntry> 
     <Data> 
      <Attribute name="TypeSubCause">EMB</Attribute> 
     </Data> 
     <WorkflowModelElement>ITPSPotential</WorkflowModelElement> 
     <EventType>Start</EventType> 
     <TimeStamp>2013-10-03T09:15:32+10.00</TimeStamp> 
     <Originator>R_Team</Originator> 
     </AuditTrailEntry> 
    </ProcessInstance> 
    </Process> 
</WorkflowLog> 

генерирующего SQL тот же идентификатор в это

SELECT '@id' = m1.TypeCause , 
     (SELECT '@id' = m2.MTypeNumber , 
        (SELECT 'TypeSubCause' AS [Data/Attribute/@name] , 
           m3.[TypeSubCause] AS [Data/Attribute/*] , 
           m3.[Subject] AS [WorkflowModelElement] , 
           'Start' AS [EventType] , 
           m3.[date] AS [TimeStamp] , 
           m3.[AssignedGroup] AS [Originator] 
         FROM  #CombinedDataSets M3 
         WHERE  m3.TypeCause = 'C_Only' 
           AND m2.MTypeNumber = m3.MTypeNumber 
           AND m2.Subject = m3.Subject 
           AND m2.date = m3.date 
        FOR 
         XML PATH('AuditTrailEntry') , 
          TYPE 
        ) 
      FROM  #CombinedDataSets m2 
      WHERE  m2.TypeCause = 'C_Only' 
        AND m1.MTypeNumber = m2.MTypeNumber 
        AND m1.Subject = m2.Subject 
        AND m1.date = m2.date 
     FOR 
      XML PATH('ProcessInstance') , 
       TYPE 
     ) 
FROM #CombinedDataSets m1 
WHERE m1.TypeCause = 'C_Only' 
ORDER BY m1.TypeCause , 
     m1.MTypeNumber , 
     m1.date 
FOR  XML PATH('Process') , 
      ROOT('WorkflowLog') 

Добавлены - Пример данные

Answer 1

Добавить group by в ваш запрос:

select 
    m1.TypeCause as [@id1], 
    (
     select 
      m2.MTypeNumber as [@id], 
      (
       select 
        'TypeSubCause' as [Data/Attribute/@name], 
        m3.[TypeSubCause] as [Data/Attribute], 
        m3.[Subject] as [WorkflowModelElement], 
        'Start' as [EventType], 
        m3.[date] as [TimeStamp], 
        m3.[AssignedGroup] as [Originator], 
       from dbo.CombineDataSets as m3 
       where 
        m3.LossCause = 'C_Only' and 
        m3.MTypeNumber = m2.MTypeNumber 
        m3.Subject = m2.Subject and 
        m3.date = m2.date 
       for xml path('AuditTrailEntry'), type 
      ) 
     from dbo.CombineDataSets as m2 
     where 
      m2.TypeCause = 'Contents Only' and 
      m2.MTypeNumber = m1.MTypeNumber 
      m2.Subject = m1.Subject 
      m2.date = m1.date 
     for xml path('ProcessInstance'), type 
    ) 
from dbo.CombineDataSets as m1 
where m1.TypeCause='C_Only' 
group by m1.TypeCause, m1.date, m1.MTypeNumber, m1.Subject 
order by m1.TypeCause 
for xml path('Process'), root('WorkflowLog') 

Answer 2

Роман был правильным, вопрос был с моей группировкой, но и с которой оператор присоединяется.

select 
    m1.TypeCause as [@id1], 
    (
    SELECT m2.MTypeNumber as [@id], 
      (
       select 

        'TypeSubCause' as [Data/Attribute/@name], 
        m3.[TypeSubCause] as [Data/Attribute], 
        m3.[Subject] as [WorkflowModelElement], 
        'Start' as [EventType], 
        m3.[date] as [TimeStamp], 
        m3.[AssignedGroup] as [Originator] 
       from #CombinedDataSets as m3 
       where 
       m3.MTypeNumber=m2.MTypeNumber 
       and m3.TypeCause=m2.TypeCause 
       for xml path('AuditTrailAudit'),type 
      )  
    from #CombinedDataSets as m2 
where 
m2.TypeCause='C_Only' 
group by m2.TypeCause, m2.MTypeNumber 
for XML path('ProcessInstance'),type 
) 
from #CombinedDataSets as m1 
where 
    m1.TypeCause='Contents Only' 
group by 
m1.TypeCause 
For XML path('Process'),Root('WorkflowLog')
