SQL服务器 - ChildNode名

Question

我有这个疑问

;WITH history_cte AS 
(
    SELECT 
    ActivityId [id] 
    , Added [activityDate] 
    , [Year] [year] 
    , Make [make] 
    , Model [model] 
    , Engine [engine] 
    , MricId [mricId] 
    , Display [activityDescription] 
    , [Header] [header] 
    , [VehicleText] [vehicleDescription] 
    , ob = CONVERT(VARCHAR(10), Added, 121) 
    FROM @top20Activities Activities   
) 
, historyDistinct_cte AS (SELECT DISTINCT [header], ob FROM history_cte) 

SELECT 
    Activities.[header] 
    , (
     SELECT 
      id 
      , activityDate 
      , [year] 
      , make 
      , model 
      , engine 
      , mricId 
      , activityDescription 
      , vehicleDescription 
     FROM history_cte Activity 
     WHERE [header] = Activities.[header] 
     ORDER BY ob DESC 
     FOR XML AUTO, TYPE 
    ) 
FROM historyDistinct_cte Activities 
ORDER BY Activities.ob DESC 
FOR XML AUTO, TYPE, ROOT ('ActivityHistory')  

它产生[近]的XML我所需要的。该子节点被简单地命名为错误的。我尝试了很多次切换别名，并且无法为我的生活找出正确的方法。我得到这个XML

如何纠正问题，使[活动]子节点正确命名。我觉得我很亲密。感谢您的帮助，提示或技巧。

干杯圣地亚哥，CK〜

Answer 1

你能尝试一下本作最终SELECT？

SELECT 
    Activities.[header], 
    (SELECT 
      id 
      , activityDate 
      , [year] 
      , make 
      , model 
      , engine 
      , mricId 
      , activityDescription 
      , vehicleDescription 
    FROM history_cte Activity 
    WHERE [header] = Activities.[header] 
    ORDER BY ob DESC 
    FOR XML PATH('Activity'), TYPE 
    ) 
FROM historyDistinct_cte Activities 
ORDER BY Activities.ob DESC 
FOR XML AUTO, TYPE, ROOT ('ActivityHistory') 

我代替嵌套选择FOR XML AUTO, TYPE与FOR XML PATH('Activity'), TYPE - 这是否你在寻找什么？
