轉換使用XMLTABLE和XPath

我試圖提取如下XML形式爲行和列，但沒有得到它想要的格式轉換使用XMLTABLE和XPath

XML XML的Clob： -

對於每一個值提取，我得到3空白並連續請幫助這個值，我在XML的新的和非常困惑，究竟我做錯了

我的答案有點快，我的答案是SQL Server語法......哪個DBMS是你的（供應商和版本）？標籤'sql'是不夠的... – Shnugo

由於下面的評論添加了'oracle10g'標籤... – Shnugo

試試這樣說：

DECLARE @xml XML= 
'Your XML here';

- 第一個CTE發現外操作數和號碼他們

WITH OuterOperands AS 
(
    SELECT ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS OperandID 
      ,cond.value('@expressionType','nvarchar(100)') AS ConditionType 
      ,o1.value('@expressionType','nvarchar(100)') AS OperandType 
      ,o1.query('.') AS Operand 
    FROM @xml.nodes('/QualificationCriterion/Condition') AS A(cond) 
    OUTER APPLY cond.nodes('Operands/Operand') AS B(o1) 
)

--Second CTE找到最外層的操作數和號碼他們

下面內的操作數

,InnerOperands AS 
(
    SELECT ROW_NUMBER() OVER(PARTITION BY OperandID ORDER BY (SELECT NULL)) AS InnerOperandID 
      ,OuterOperands.* 
      ,iop.query('.') AS InnerOperand 
      ,iop.value('(LeftOperand/@attributeName)[1]','nvarchar(100)') AS LeftAttributeName 
      ,COALESCE(iop.value('(RightOperand/@value)[1]','nvarchar(100)'),iop.value('(RightOperand/@name)[1]','nvarchar(100)')) AS RightValue 
    FROM OuterOperands 
    OUTER APPLY Operand.nodes('Operand/Operands/Operand') AS A(iop) 
)

--Final SELECT出示你的預期輸出

SELECT ConditionType 
     ,OperandID 
     ,InnerOperandID 
     ,@xml.value('(/QualificationCriterion/@name)[1]','nvarchar(100)') AS QualificationCriterionName 
     ,LeftAttributeName 
     ,RightValue 
     ,OperandType 
     --,Operand --(find the rest here, if needed) 
     --,InnerOperand --(find the rest here, if needed) 
FROM InnerOperands

結果

注意：您應該添加ORDER BY OperandID,InnerOperandID以獲得正確的排序順序...

我正在使用oracle 10g.can你也幫助我的Oracle以及 –

@ChandanBikash，那麼，一個不應該反應如此之快:-) ......可能是你明白了，你可以將這種方法轉化爲你的語言...... – Shnugo
