sql - 没有获得适当的结构

Question

我有这样的存储过程:

CREATE PROCEDURE [dbo].[Poll_EDI834_5010] 
AS 
BEGIN 
SELECT     Header.ST01,   
           Line.PER04__CommunicationNumber ,
           (SELECT  Member_Ref.REF01_ReferenceIdentificationQualifier
            FROM    EDI834_5010_2000_RefLoop Member_Ref  
            WHERE   Member_Ref.Id_Header = Header.BGN02__TransactionSetIdentifierCode             
            AND     Member_Ref.Id_Loop2000 = Line.Member_Id
            FOR XML AUTO, ELEMENTS, TYPE),    
           VLine.HD01_MaintenanceTypeCode,    
           (SELECT  ClaimDTP.DTP01__DateTimeQualifier 
            FROM    EDI834_5010_2300_DTPLoop ClaimDTP      
            WHERE   ClaimDTP.Id_Header = Header.BGN02__TransactionSetIdentifierCode      
            AND     ClaimDTP.Id_Loop2000 = Line.Member_Id      
            AND     ClaimDTP.Id_Loop2300 = VLine.Id_Claim      
            FOR XML AUTO, ELEMENTS, TYPE) 
FROM       EDI834_5010_Header   Header  
JOIN       EDI834_5010_2000     Line   ON Header.BGN02__TransactionSetIdentifierCode = Line.Header_Id 
JOIN       EDI834_5010_2300Loop VLine  ON Header.BGN02__TransactionSetIdentifierCode = VLine.Id_Header_Id andVLine.Id_Loop2000=Line.Member_Id
FOR XML AUTO, ELEMENTS 
END 
GO 

我得到的数据结构如下:

<Header>
     <Line>
        <MemberRef> </MemberRef>
        <MemberRef> </MemberRef>
        <VLine>
           <Claim_DTP>  </Claim_DTP>
           <Claim_DTP>  </Claim_DTP>
         </VLine>
     </Line>
 </Header>

我的问题是我希望数据看起来像这样:

  <Header>
    <Line>
       <MemberRef> </MemberRef>
       <MemberRef> </MemberRef>
       <VLine>
         <Claim_DTP>  </Claim_DTP>
         <Claim_DTP>  </Claim_DTP>
      </VLine>
       <VLine>
         <Claim_DTP>  </Claim_DTP>
         <Claim_DTP>  </Claim_DTP>
       </VLine>
   </Line>
</Header>

为什么我的 VLine 节点不重复？但是当我删除子查询 Member_Ref 时，我得到了适当的结构。但我需要那个子查询。有什么办法可以实现这个结构吗？
