How to get multiple column data in a comma separated string?

I am getting data like

Result
------
 10
 23 
 21

But i want开发者_StackOverflow中文版 to get data in the following format.

Result
------
10, 23, 21

How to get that in a Query? Thanks in advance for any help :)

Sample code that doesn't use stored procedure :) ...

USE AdventureWorks
GO
-- Check Table Column
SELECT Name
FROM HumanResources.Shift
GO
-- Get CSV values
SELECT SUBSTRING(
(SELECT ',' + s.Name
FROM HumanResources.Shift s
ORDER BY s.Name
FOR XML PATH('')),2,200000) AS CSV
GO

Edit:

For SQL-Server 2000, take a look here:

How to Format Query Result as Comma Separated Values (CSV)

Here is one way, There is a student table having studentName column with datatype as nvarchar(50) then following query will give you student names as comma separated values,

DECLARE @VALUES NVARCHAR(1000)
SELECT @VALUES = COALESCE(@VALUES + ',','') + CAST(STUDENTNAME AS NVARCHAR(50)) FROM STUDENT
SELECT @VALUES
