采用以下TSQL

SELECT 
    o.id as '@id',
    (SELECT 
         op.id as '@orderid'
     FROM 
         Orders o
     INNER JOIN 
         OrderParts op ON o.id = op.orderId
     FOR XML PATH ('orderpart'), TYPE)
FROM 
    Orders o
FOR XML PATH ('order'), ROOT('application')

从这些表生成.

命令

Id   type
----------------
1    Pending
2    Active

订购零件

id   orderid
-------------
1       1
2       1
3       3
4       2

它生成这个XML

<application>
  <order id="1">
    <orderpart orderid="1" />
    <orderpart orderid="2" />
    <orderpart orderid="3" />
    <orderpart orderid="4" />
  </order>
  <order id="2">
    <orderpart orderid="1" />
    <orderpart orderid="2" />
    <orderpart …
