使用XML文件更新SQL Server列

我可以使用XML文件將數據正確地插入到表中，但沒有我想知道是否可以使用XML文件更新列。我有這樣的插入，它的工作原理：使用XML文件更新SQL Server列

IF @LAST_Question <> @QuestionText 
BEGIN 
    insert into [TempDataBase].[dbo].TestQuestion (QuestionType, Question_Text, Questionaire_ID, Filter) 
    VALUES (@QuestionType, @QuestionText, @Questionaire_ID,@Filter) 

    select @newQuestion_ID = SCOPE_IDENTITY() 
END 

INSERT INTO [TempDataBase].[dbo].TestPossible(Q_ID, Expl, Rev, P_A_T, QType) 
VALUES (@newQuestion_ID, @RequiresExplanation, @ReviewRequired, @Value, @QuestionType) 

SET @LAST_Question = @QuestionText

但是當我嘗試和更新，只需要把最後一個值的XML

UPDATE [TempDataBase].[dbo].TestPossible 
SET Expl = @RequiresExplanation, 
    Rev = @ReviewRequired, 
    P_A_T = @Value, 
    QType = @QuestionType 
WHERE Q_ID = @ID

現在我有一個光標定義及其他語句來使插入和更新運行，所以沒有必要建議我添加這些語句，我沒有添加它們來保存頁面上的擁塞。如果需要，我可以顯示XML。最主要的是我有多個@Value，它只在第一個問題中插入所需的次數（兩個用於第一個問題，三個用於第二個）

有沒有人有建議來完成這個？

，這裏是我應得的XML數據

DECLARE @XmlString as XML 

select @XmlString = cast(x as XML) 
from openrowset(bulk 'C:\xml_ID.xml',single_blob) as T(x) 

--SET UP A CURSOR to walk through the uploaded XML table 
DECLARE cur CURSOR LOCAL for 
     SELECT 
       Question_ID = XTBL .value('(../../ID)[1]', 'bigint'), 
       QuestionText = XTbl.value('(../../QuestionText)[1]', 'varchar(200)'), 
       QuestionType = XTbl.value('(../../QuestionType)[1]', 'bigint'), 
       Questionaire_ID = XTbl.value('(../../QuestionaireID)[1]', 'bigint'), 
       Filter = XTbl.value('(../../Filter)[1]', 'bigint'), 
       Value = XTbl.value('(Value)[1]', 'varchar(400)'), 
       RequiresExplanation = XTbl.value('(RequiresExplanation)[1]', 'int'), 
       ReviewRequired = XTbl.value('(ReviewRequire)[1]', 'char(1)') 
     FROM 
      @XmlString.nodes('/Questions/Question/PossibleAnswers/PossibleAnswer') AS XD(XTbl)

需要xml文件以及如何從xml代碼中提取值 – radar 2014-11-05 19:36:35

@RADAR是您需要的嗎？ – 2014-11-05 19:42:27

看起來不錯，其中更新語句中使用的ID集在哪裏修改此ID？ – radar 2014-11-05 19:52:24

更新表TestPossible使用Question_ID

，如果我們做以下面的示例輸入爲例，同一個問題id有兩個值，只有一行，即最後一行匹配並更新。

Question_ID Value 
2422 "yes it did" 
2422 "no it did not"

一種選擇是消除這些問題的所有行和更新新的可能值或者你需要有另一種獨特的密鑰識別各個可能的答案值。
