SQL Server 中的相应功能是SELECT ... FOR XML 查询。来自docs的EG：

USE AdventureWorks2012;  
GO  
SELECT E.BusinessEntityID "@EmpID",   
        'Example of using node tests such as text(), comment(), processing-instruction()'                as "comment()",  
        'Some PI'                   as "processing-instruction(PI)",  
        'Employee name and address data' as "text()",  
        'middle name is optional'        as "EmpName/text()",  
        FirstName                        as "EmpName/First",   
        MiddleName                       as "EmpName/Middle",   
        LastName                         as "EmpName/Last",  
        AddressLine1                     as "Address/AddrLine1",  
        AddressLine2                     as "Address/AddrLIne2",  
        City                             as "Address/City"  
FROM   HumanResources.Employee AS E  
INNER JOIN Person.Person AS P   
    ON P.BusinessEntityID = E.BusinessEntityID  
INNER JOIN Person.BusinessEntityAddress AS BAE  
    ON BAE.BusinessEntityID = E.BusinessEntityID  
INNER JOIN Person.Address AS A  
    ON BAE.AddressID = A.AddressID  
WHERE  E.BusinessEntityID=1  
FOR XML PATH;
