SQL Server 2014查询到特定的XML格式

Question

I have been asked to provide some data in XML format to a 3rd party company. I am using SQL Server 2014 for this. I cannot find anything anywhere which relates to the format that has been requested.

The format is as follows:

<Item>
    <p:attribute_name="Product">Coat</p:attribute>
    <p:attribute_name="Colour">Purple</p:attribute>
    <p:attribute_name="Material">Polyester, Nylon</p:attribute>
</Item>

The SQL code to get this is:

SELECT
    Product,
    Colour,
    Material
FROM Products

Which returns this:

ID    Product    Colour    Material
1     Coat       Purple    Polyester, Nylon

I would like to know if it is at all possible to return the results of the query into the XML format provided.

Any help is appreciated

Answer 1

As stated in my comment, your target format is not valid and a namespace is missing. My magic glass bulb tells me, that you are looking for something like this:

EDIT: Sorry, my first code mixed the captions!

CREATE TABLE dbo.Test(ID INT,Product VARCHAR(100),Colour VARCHAR(100),Material VARCHAR(100));
INSERT INTO dbo.Test VALUES(1,'Coat','Purple','Polyester,Nylon');

WITH XMLNAMESPACES('test' AS p)
SELECT 'Product' AS [p:attributName/@name]
      ,Product AS [p:attributName]
      ,''
      ,'Colour' AS [p:attributName/@name]
      ,Colour AS [p:attributName]
      ,''
      ,'Material' AS [p:attributName/@name]
      ,Material AS [p:attributName]
FROM dbo.Test
FOR XML PATH('Item')

DROP TABLE dbo.Test;

/*
<Item xmlns:p="test">
  <p:attributName name="Product">Coat</p:attributName>
  <p:attributName name="Colour">Purple</p:attributName>
  <p:attributName name="Material">Polyester,Nylon</p:attributName>
</Item>
*/

DECLARE @t TABLE (
    ID INT IDENTITY,
    Product VARCHAR(50),
    Colour VARCHAR(50),
    Material VARCHAR(150)
)
INSERT INTO @t (Product, Colour, Material)
VALUES
    ('Coat', 'Purple', 'Polyester, Nylo'),
    ('test', 'test2', 'test3')

;WITH XMLNAMESPACES ('p' as p)
SELECT ID, val
FROM @t
CROSS APPLY (
    SELECT val = (
        SELECT
            [@name] = t2.id,
            [text()] = t2.[value]
        FROM (
            VALUES
                ('Product', Product),
                ('Colour', Colour),
                ('Material', Material)
        ) t2 (id, value)
        FOR XML PATH('p:attribute'), ROOT('Item'), TYPE
    )
) t2
