SQL中的多个XML标记

Question

我有来自_temp的select *的以下数据： -

我想生成下面的xml： -

<xml>
  <StoryData>
    <UserStoryId>141204</UserStoryId>
    <Description>Customer can see the applicable discount on the quote and change in premium.</Description>
    <Summary>Customer can see the applicable discount on the quote and change in premium.</Summary>
    <UserStoryID>141204</UserStoryID>
    <VagueWord>and</VagueWord>
    <VagueWord>applicable</VagueWord>
  </StoryData>

  <StoryData>
    <UserStoryId>141205</UserStoryId>
    <Description>Customer can see the applicable discount on the quote and change in premium.</Description>
    <Summary>Customer can see the applicable discount on the quote and change in premium.</Summary>
    <UserStoryID>141205</UserStoryID>
    <VagueWord>and</VagueWord>
    <VagueWord>applicable</VagueWord>
  </StoryData>  
</xml>

我试过以下查询： -

select distinct t1.UserStoryId,t1.Description,t1.Summary,t1.UserStoryID,t2.VagueWord
from _temp t1 left join
(
 select UserStoryId,VagueWord from _temp
) t2
on t1.UserStoryId=t2.UserStoryId
where t1.UserStoryId in (141204,141205)

FOR XML PATH('StoryData')

,ROOT('xml'),type

产生的是： -

<xml>
  <StoryData>
    <UserStoryId>141204</UserStoryId>
    <Description>Customer can see the applicable discount on the quote and change in premium.</Description>
    <Summary>Customer can see the applicable discount on the quote and change in premium.</Summary>
    <UserStoryID>141204</UserStoryID>
    <VagueWord>and</VagueWord>
  </StoryData>
  <StoryData>
    <UserStoryId>141204</UserStoryId>
    <Description>Customer can see the applicable discount on the quote and change in premium.</Description>
    <Summary>Customer can see the applicable discount on the quote and change in premium.</Summary>
    <UserStoryID>141204</UserStoryID>
    <VagueWord>applicable</VagueWord>
  </StoryData>
  <StoryData>
    <UserStoryId>141205</UserStoryId>
    <Description>Customer can see the applicable discount on the quote and change in premium.</Description>
    <Summary>Customer can see the applicable discount on the quote and change in premium.</Summary>
    <UserStoryID>141205</UserStoryID>
    <VagueWord>and</VagueWord>
  </StoryData>
  <StoryData>
    <UserStoryId>141205</UserStoryId>
    <Description>Customer can see the applicable discount on the quote and change in premium.</Description>
    <Summary>Customer can see the applicable discount on the quote and change in premium.</Summary>
    <UserStoryID>141205</UserStoryID>
    <VagueWord>applicable</VagueWord>
  </StoryData>
</xml>

我们可以看到，VagueWord是多个，StoryData标签正在为特定的UserStoryID重复。

我希望不同的UserStoryID和Vagueword标签的不同标签在内部重复，如上所示。

我怎样才能做到这一点？

您可以使用子查询：

;WITH cte AS (
SELECT *
FROM (VALUES
(141204,'Customer can see the applicable discount on the quote and change in premium.','Customer can see the applicable discount on the quote and change in premium.','and'),
(141204,'Customer can see the applicable discount on the quote and change in premium.','Customer can see the applicable discount on the quote and change in premium.','applicable'),
(141205,'Customer can see the applicable discount on the quote and change in premium.','Customer can see the applicable discount on the quote and change in premium.','and'),
(141205,'Customer can see the applicable discount on the quote and change in premium.','Customer can see the applicable discount on the quote and change in premium.','applicable')
) as t(UserStoryId, [Description], Summary, VagueWord)
)

SELECT  UserStoryId, 
        [Description], 
        Summary, 
        (SELECT VagueWord
        FROM cte
        WHERE UserStoryId = c.UserStoryId
        FOR XML PATH(''),TYPE)
FROM cte c
GROUP BY  UserStoryId, 
        [Description], 
        Summary
FOR XML PATH('StoryData'),ROOT('xml'),TYPE

输出：

<xml>
  <StoryData>
    <UserStoryId>141204</UserStoryId>
    <Description>Customer can see the applicable discount on the quote and change in premium.</Description>
    <Summary>Customer can see the applicable discount on the quote and change in premium.</Summary>
    <VagueWord>and</VagueWord>
    <VagueWord>applicable</VagueWord>
  </StoryData>
  <StoryData>
    <UserStoryId>141205</UserStoryId>
    <Description>Customer can see the applicable discount on the quote and change in premium.</Description>
    <Summary>Customer can see the applicable discount on the quote and change in premium.</Summary>
    <VagueWord>and</VagueWord>
    <VagueWord>applicable</VagueWord>
  </StoryData>
</xml>
