1、使用AUTO模式检索嵌套数据

select Cust.CustomerID CustID,CustomerType,
SalesOrderID from Sales.Customer Cust
join Sales.SalesOrderHeader [order]
on Cust.CustomerID=[order].CustomerID
order by Cust.CustomerID
for XML AUTO

结果如下：

<Cust CustID="1" CustomerType="S">
<order SalesOrderID="43860" />
<order SalesOrderID="44501" />
<order SalesOrderID="45283" />
<order SalesOrderID="46042" />
</Cust>
<Cust CustID="2" CustomerType="S">
<order SalesOrderID="46976" />
<order SalesOrderID="47997" />
<order SalesOrderID="49054" />
<order SalesOrderID="50216" />
<order SalesOrderID="51728" />
<order SalesOrderID="57044" />
<order SalesOrderID="63198" />
<order SalesOrderID="69488" />
</Cust>

2、作为元素检索数据

select Cust.CustomerID CustID,CustomerType,
SalesOrderID from Sales.Customer Cust
join Sales.SalesOrderHeader [order]
on Cust.CustomerID=[order].CustomerID
order by Cust.CustomerID
for XML AUTO,ELEMENTS

结果如下：

<Cust>
<CustID>1</CustID>
<CustomerType>S</CustomerType>
<order>
<SalesOrderID>43860</SalesOrderID>
</order>
<order>
<SalesOrderID>44501</SalesOrderID>
</order>
<order>
<SalesOrderID>45283</SalesOrderID>
</order>
<order>
<SalesOrderID>46042</SalesOrderID>
</order>
</Cust>
<Cust>
<CustID>2</CustID>
<CustomerType>S</CustomerType>
<order>
<SalesOrderID>46976</SalesOrderID>
</order>
<order>
<SalesOrderID>47997</SalesOrderID>
</order>
<order>
<SalesOrderID>49054</SalesOrderID>
</order>
<order>
<SalesOrderID>50216</SalesOrderID>
</order>
<order>
<SalesOrderID>51728</SalesOrderID>
</order>
<order>
<SalesOrderID>57044</SalesOrderID>
</order>
<order>
<SalesOrderID>63198</SalesOrderID>
</order>
<order>
<SalesOrderID>69488</SalesOrderID>
</order>
</Cust>

3、添加根节点

select Cust.CustomerID CustID,CustomerType,
SalesOrderID from Sales.Customer Cust
join Sales.SalesOrderHeader [order]
on Cust.CustomerID=[order].CustomerID
order by Cust.CustomerID
for XML AUTO,ELEMENTS,ROOT('Orders')

结果如下：

<Orders>
<Cust>
<CustID>1</CustID>
<CustomerType>S</CustomerType>
<order>
<SalesOrderID>43860</SalesOrderID>
</order>
<order>
<SalesOrderID>44501</SalesOrderID>
</order>
<order>
<SalesOrderID>45283</SalesOrderID>
</order>
<order>
<SalesOrderID>46042</SalesOrderID>
</order>
</Cust>
<Cust>
<CustID>2</CustID>
<CustomerType>S</CustomerType>
<order>
<SalesOrderID>46976</SalesOrderID>
</order>
<order>
<SalesOrderID>47997</SalesOrderID>
</order>
<order>
<SalesOrderID>49054</SalesOrderID>
</order>
<order>
<SalesOrderID>50216</SalesOrderID>
</order>
<order>
<SalesOrderID>51728</SalesOrderID>
</order>
<order>
<SalesOrderID>57044</SalesOrderID>
</order>
<order>
<SalesOrderID>63198</SalesOrderID>
</order>
<order>
<SalesOrderID>69488</SalesOrderID>
</order>
</Cust>
</Orders>
