如何从SQL生成xml，其中Column Name为prop，Column Value为value MSSQL Server

Question

我有一个SQL表，其中包含以下列

1. 命名
2. 的 FatherName
3. 的 MotherName
4. 的国籍

我想通过SQL Query生成XML，结果如下

<Customer>
<Prop ID="Name" ValStr="CustName" />
<Prop ID="FatherName" ValStr="Mr.xxx" />
<Prop ID="MotherName" ValStr="Mrs.yyy" />
<Prop ID="Nationality" ValStr="ZZZ" />
</Customer>

我怎样才能得到这个。请帮帮我

Answer 1

试试这样：

DECLARE @tbl TABLE(Name VARCHAR(100),FatherName VARCHAR(100),MotherName VARCHAR(100),Nationality VARCHAR(100));
INSERT INTO @tbl VALUES
 ('Name1','FatherName1','MotherName1','Nationality1')
,('Name2','FatherName2','MotherName2','Nationality2');

SELECT 
    'Name' AS [Prop/@ID]
   ,Name AS [Prop/@ValStr]
   ,''
   ,'FatherName' AS [Prop/@ID]
   ,FatherName AS [Prop/@ValStr]
   ,''
   ,'MotherName' AS [Prop/@ID]
   ,MotherName AS [Prop/@ValStr]
   ,''
   ,'Nationality' AS [Prop/@ID]
   ,Nationality AS [Prop/@ValStr]
FROM @tbl
FOR XML PATH('Customer'),ROOT('root')

结果

<root>
  <Customer>
    <Prop ID="Name" ValStr="Name1" />
    <Prop ID="FatherName" ValStr="FatherName1" />
    <Prop ID="MotherName" ValStr="MotherName1" />
    <Prop ID="Nationality" ValStr="Nationality1" />
  </Customer>
  <Customer>
    <Prop ID="Name" ValStr="Name2" />
    <Prop ID="FatherName" ValStr="FatherName2" />
    <Prop ID="MotherName" ValStr="MotherName2" />
    <Prop ID="Nationality" ValStr="Nationality2" />
  </Customer>
</root>

需要空列（,''）来告诉引擎启动新元素。否则你会收到一个错误，因为一个属性不能在同一个元素中存活两次。

嗨，您可以使用 FOR XML RAW 实用程序

SELECT NAME, FATHERNAME, MOTHERNAME, NATIONALITY
FROM table_name 
FOR XML RAW ('ID');
