早安技師，根據文檔類型定義XML的動態表創建

任何人都可以分享您的專業知識。

我有一個文檔類型定義的XML文檔（1GB大小）。

我需要將數據加載到sql表中，但挑戰是必須在運行時創建的表結構依賴於.dtd文件。

的.dtd文件是不斷根據客戶的客戶

我是新來的XML更改，請幫幫我。如果需要，我可以提供xml和.dtd。

代碼我已經用來拉從XML數據表

;With Cte 

AS 

(SELECT i.value('(../@action)[1]','varchar(20)') AppAction, 

     i.value('(../@id)[1]','varchar(20)') AppId, 

     i.value('.','varchar(20)') Notes, 

    i.value('(../BaseVehicle/@id)[1]','varchar(20)') BaseVehicle, 

     k.value('(./Qual/@id)[1]','varchar(20)') Qual, 

    i.value('(../Qty)[1]','varchar(20)') Qty, 

    i.value('(../PartType/@id)[1]','varchar(20)') PartType, 

    i.value('(../SubModel/@id)[1]','varchar(20)') SubModel, 
    i.value('(../EngineBase/@id)[1]','varchar(20)') EngineBase, 
    i.value('(../EngineVIN/@id)[1]','varchar(20)') EngineVIN, 
    k.value('(./MfrLabel)[1]','varchar(20)') MfrLabel, 
    i.value('(../Position/@id)[1]','varchar(20)') PositionId, 
    i.value('(../Part)[1]','varchar(20)') Part, 
    k.value('(./Qual/param/@value)[1]','varchar(20)') ParamValue, 
    j.value('.','varchar(20)') RecordCount 

FROM @X.nodes('AMUL/App[@action="A"]/Note') x(i) 

OUTER APPLY x.i.nodes('../../Footer/RecordCount')y(j) 

OUTER APPLY y.j.nodes('../../App')z(k)) 

SELECT 


AppAction,AppId,BaseVehicle,Qual,Qty,PartType,MfrLabel,PositionId,Part,ParamValue,SubModel,EngineBase,EngineVIN,RecordCount, 

     STUFF((SELECT ' ; ' + Notes 

      FROM Cte X WHERE X.BaseVehicle = Y.BaseVehicle 

      GROUP BY BaseVehicle,Notes 

      FOR XML PATH('')), 1, 2, '') Note     

FROM Cte Y 

GROUP BY 
BaseVehicle,AppAction,AppId,Qual,Qty,PartType,MfrLabel,PositionId,Part,ParamValue,SubModel,EngineBase,EngineVIN,RecordCount

由於一噸。

您提供的將是有幫助的任何額外的細節，但是從我的頭頂，如果我不得不做這個任務，我不想嚴格做到這一點在SQL，但發展的外部工具來做到這一點在.NET或其他您熟悉的語言中。 – Jeremy

感謝您的幫助。請建議。我被困在這裏。 :)我們可以在這裏附加.dtd或xml文件。 – Shan

你有什麼編程經驗？ – Jeremy

這是第一次嘗試：

它將創建（實際上只是聲明）四個表（文件，應用程序，QUAL和票據） 你的數據被插入與創建外鍵。 最後幾行是一個完全加入結果集 我包括所有的XML節點到目標表，以確保，錯過信息不會丟失......

只是整件事複製到一個空的查詢窗口，執行和探索者最終的結果是否符合你的需求。

如果是，請不要忘記投票並接受。這花了不少努力:-)

快樂編碼！
