FOR XML RAW[, ELEMENTS ]

Data in BINARY, LONG BINARY, IMAGE, and VARBINARY columns is automatically returned in base64-encoded format when you execute a query that contains FOR XML RAW.

By default, NULL values are omitted from the result. This behavior is controlled by the for_xml_null_treatment option.

FOR XML RAW does not return a well-formed XML document because the document does not have a single root node. If a <root> element is required, one way to insert one is to use the XMLELEMENT function. For example:

SELECT XMLELEMENT( NAME root,
                   (SELECT EmployeeID AS id, GivenName AS name
                   FROM Employees FOR XML RAW) );

The attribute or element names used in the XML document can be changed by specifying aliases. The following query renames the ID attribute to product_ID:

SELECT ID AS product_ID
FROM Products
WHERE Color='black'
FOR XML RAW;

This query gives the following result:

<row product_ID="302"/>
<row product_ID="400"/>
<row product_ID="501"/>
<row product_ID="700"/>

The order of the results depend on the plan chosen by the optimizer, unless you request otherwise. If you want the results to appear in a particular order, you must include an ORDER BY clause in the query, for example:

SELECT Employees.EmployeeID, Departments.DepartmentName
FROM Employees JOIN Departments
   ON Employees.DepartmentID=Departments.DepartmentID
ORDER BY EmployeeID
FOR XML RAW;

Suppose you want to retrieve information about which department an employee belongs to, as follows:

SELECT Employees.EmployeeID, Departments.DepartmentName
FROM Employees JOIN Departments
   ON Employees.DepartmentID=Departments.DepartmentID
FOR XML RAW;

The following XML document is returned:

<row EmployeeID="102" DepartmentName="R &amp; D"/>
<row EmployeeID="105" DepartmentName="R &amp; D"/>
<row EmployeeID="160" DepartmentName="R &amp; D"/>
<row EmployeeID="243" DepartmentName="R &amp; D"/>
...
