问题描述

| 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。子节点只是简单地命名为错误。我已经尝试过多次切换别名，但终生无法找出正确的方法。我正在获取这个XML

我该如何纠正问题，以便正确地命名[Activity]子节点。我觉得我已经很近了。感谢您的帮助，提示或技巧。 在圣地亚哥欢呼，〜ck     

解决方法

您能为期末的ѭ2尝试吗？ 
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ѭ4替换为
FOR XML PATH(\'Activity\'),TYPE
-这样做能满足您的需求吗？
