在SQL服務器中將層次結構表元素轉換爲xml格式

我有兩個表，一個是代碼，另一個是子映射表，用於代表與代碼表的父子關係。在SQL服務器中將層次結構表元素轉換爲xml格式

表：代碼

Code ID | Code Value | code Group | code Desc 
1    Person 1  Accounts  cashier 
2    Person 2  Finance  teller 
3    Person 3  HR   administrator 
4    Person 4  IT   system admin

表：映射

Id (Primarykey)  | code ID | Parent Code ID (both code ID and parent code ID are foreign keys with codes table 
1      1   Null 
2      2   1 
3      3   1 
4      4   Null 
5      3   4

我需要一個輸出

<Codes> 
<CodeParent group = "Accounts"> 
    <ChildCodes group= "Finance"> 
     <CodeParent name = "person 2" desc = "teller"/> 
    </ChildCodes> 
    <ChildCodes group = "HR"> 
     <CodeParent name = "Person 3" desc = "Administrator"/> 
    <ChildCodes>  
</CodeParent > 
<CodeParent group = "IT> 
    <ChildCodes group = "HR"> 
     <CodeParent name = "Person 3" desc = "Administrator"/> 
    <ChildCodes> 
</CodeParent > 
</Root>

我用這個SQL函數嘗試，但它似乎並沒有給正確的期望輸出

ALTER FUNCTION dbo.GetPartsSubTree(@PartNumberID int) 
RETURNS XML 
BEGIN RETURN 
(SELECT codeMappingTable.codeID AS "@codeID", 
codes.codeLiteral AS "@codeLiteral", 
codes.codeGroup AS "@codeGroup", 
dbo.GetPartsSubTree(codeMappingTable.codeID) 
FROM codeMappingTable,codes 

WHERE [email protected] and codes.codeID = codeMappingTable.codeID 
ORDER BY codeMappingTable.codeID 
FOR XML PATH('CodeParent'),ROOT('ChildCodes'),TYPE) 
END 

GO 

SELECT codeMappingTable.codeID AS "@codeID", 
codes.codeLiteral AS "@codeLiteral", 
codes.codeGroup AS "@codeGroup", 
dbo.GetPartsSubTree(codeMappingTable.codeID) 
FROM codeMappingTable,codes 
WHERE codeMappingTable.ParentcodeID is null and codes.codeID = codeMappingTable.codeID 
ORDER BY codeMappingTable.codeID 
FOR XML PATH('CodeParent'),ROOT('Codes'),TYPE

請幫我解決這個問題。

在一個更大的尺度的期望輸出是如下：

declare @Codes table(ID int, CodeValue varchar(10), CodeGroup varchar(10), CodeDesc varchar(20)) 
declare @Mapping table(ID int, CodeID int, ParentCodeID int) 

insert into @Codes values

我想你的代碼的Mikael，它的工作原理然而，當我有它無法處理它，例如見下文 – Hema 2011-03-30 15:27:17

我想你的代碼的Mikael表中多個嵌套條目，它的工作原理然而，當我有多個嵌套條目（5，'Person 5'，'Accounts'，'accountant'）插入@Codes 值（6，'Person 6'，'Finance' '，'Investbanker'）插入@Mapping值（6,5，null）插入@Mapping值（7,6,1）它爲帳戶創建多個節點併爲財務創建多個節點 – Hema 2011-03-30 15:41:14

@Hema - 已更新回答你的新數據。您在第一個「accounts」節點「Finance」下添加了一個新的根項目「accounts」和新項目。那不是你想要的嗎？如果不是，請用輸入數據和預期輸出更新您的問題。 – 2011-03-30 16:41:19

的Mikael，我具有上述表 1）父在以下可能關係代碼組本身就是它自己的。 2）父代碼組驅動一個子組 3）父代碼組驅動兩個不同的子組 4）父代碼組驅動子組，並且子組intint驅動子組 5）孩子組有兩個不同的父組

當所有關係存在時，以下是所需的代碼輸出。
