如何从SQL以列名作为prop并将列值作为值MSSQL Server生成xml

Question

I have a SQL Table which has the following columns

1. Name
2. FatherName
3. MotherName
4. Nationality

I want to generate a XML by SQL Query Which will results as follows

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

How can I get this. Please help me

Answer 1

Try it like this:

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')

The result

<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>

The empty columns ( ,'' ) are needed to tell the engine to start a new element. Otherwise you'd get an error, because an attribute cannot live twice within the same element.

Hi,
You can use FOR XML RAW utility

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