Question

我正在使用XML EXPLICIT生成一个发送到另一个应用程序的XML文档。标签是标签/值，顺序很重要，因为其他应用程序将在收到的订单中显示标签和值。

这是我使用

信息的一个例子

N     |    V
_______________
Objective - XXX
State     - New York
Country   - US

我希望得到

<X>
   <T>
     <N>Objective</N>
     <V>XXX</V>
   </T>
   <T>
     <N>State</N>
     <V>New York</V>
   </T>
   <T>
     <N>Country</N>
     <V>US</V>
   </T>
</X>

然而我会按N字母按字母顺序排序

<X>
   <T>
     <N>Country</N>
     <V>US</V>
   </T>
   <T>
     <N>Objective</N>
     <V>XXX</V>
   </T>
   <T>
     <N>State</N>
     <V>New York</V>
   </T>

</X>

这是查询

我在最后的输出中没有看到订单...

没有它你就无法控制生成xml的顺序。

如果您不知道如何向工会申请订单，请参阅此问题：SQL Query - Using Order By in UNION

如何使XML EXPLICIT * NOT *按字母顺序重新排序？
