Question

我有这个查询

;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')

它生成[几乎]我需要的XML。子节点简称错误。我已经尝试过多次切换别名，并且不能为我的生活找出正确的方法。我正在获取此XML

如何更正问题，以便正确命名[Activity]子节点。我觉得我很亲密。感谢您提供任何帮助，提示或技巧。

你能为最后的SELECT尝试这个吗？

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')

我将嵌套选择中的FOR XML AUTO, TYPE替换为FOR XML PATH('Activity'), TYPE - 这样做是否符合您的要求？
