在SQL服务器中将层次结构表元素转换为xml格式

我有两个表，一个是代码，另一个是子映射表，用于代表与代码表的父子关系。在SQL服务器中将层次结构表元素转换为xml格式

表：代码

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

我需要一个输出

<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>

我用这个SQL函数尝试，但它似乎并没有给正确的期望输出

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

请帮我解决这个问题。

在一个更大的尺度的期望输出是如下：

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 
(1, 'Person 1', 'Accounts', 'cashier'), 
(2, 'Person 2', 'Finance', 'teller'), 
(3, 'Person 3', 'HR',  'administrator'), 
(4, 'Person 4', 'IT',  'system admin'), 
(5, 'Person 5', 'Accounts', 'accountant'), 
(6, 'Person 6', 'Finance', 'Investbanker') 

insert into @Mapping values 
(1, 1, null), 
(2, 2, 1), 
(3, 3, 1), 
(4, 4, null), 
(5, 3, 4), 
(6, 5, null), 
(7, 6, 1) 

select 
    CRoot.CodeGroup as '@group', 
    (select 
    CChild.CodeGroup as '@group', 
    CChild.CodeValue as 'CodeParent/@name', 
    CChild.CodeDesc as 'CodeParent/@desc' 
    from @Mapping as MChild 
    inner join @Codes as CChild 
     on MChild.CodeID = CChild.ID 
    where MChild.ParentCodeID = MRoot.ID 
    for xml path('ChildCodes'), type) 
from @Mapping as MRoot 
    inner join @Codes as CRoot 
    on MRoot.CodeID = CRoot.ID 
where 
    MRoot.ParentCodeID is null 
for xml path('CodeParent'), root('Codes')

结果

<Codes> 
    <CodeParent group="Accounts"> 
    <ChildCodes group="Finance"> 
     <CodeParent name="Person 2" desc="teller" /> 
    </ChildCodes> 
    <ChildCodes group="HR"> 
     <CodeParent name="Person 3" desc="administrator" /> 
    </ChildCodes> 
    <ChildCodes group="Finance"> 
     <CodeParent name="Person 6" desc="Investbanker" /> 
    </ChildCodes> 
    </CodeParent> 
    <CodeParent group="IT"> 
    <ChildCodes group="HR"> 
     <CodeParent name="Person 3" desc="administrator" /> 
    </ChildCodes> 
    </CodeParent> 
    <CodeParent group="Accounts" />

我想你的代码的Mikael，它的工作原理然而，当我有它无法处理它，例如见下文 – Hema 2011-03-30 15:27:17

我想你的代码的Mikael表中多个嵌套条目，它的工作原理然而，当我有多个嵌套条目（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） 它为帐户创建多个节点并为财务创建多个节点 – Hema 2011-03-30 15:41:14

@Hema - 已更新回答你的新数据。您在第一个“accounts”节点“Finance”下添加了一个新的根项目“accounts”和新项目。那不是你想要的吗？如果不是，请用输入数据和预期输出更新您的问题。 – 2011-03-30 16:41:19

的Mikael，我具有上述表 1）父在以下可能关系代码组本身就是它自己的。 2）父代码组驱动一个子组 3）父代码组驱动两个不同的子组 4）父代码组驱动子组，并且子组intint驱动子组 5）孩子组有两个不同的父组

当所有关系存在时，以下是所需的代码输出。
