The Group_CONCAT is only MySQL and not sql server.

If you are using SQL 2005 and above you could do something like this:

SQL

SELECT DISTINCT customerId, (SELECT CONVERT(VARCHAR(MAX), (SELECT LTRIM(UPPER(ISNULL(ProductName,'')) + ',')
	FROM tblOrder o
	WHERE o.CustomerId = orders.CustomerId
	FOR XML PATH('')))) AS Products
FROM tblOrder orders
ORDER BY CustomerId

OR using STUFF()

SQL

SELECT DISTINCT customerId, STUFF((SELECT ',' + ProductName FROM tblOrder FOR XML PATH('')), 1, 1, '') AS Products
FROM tblOrder orders
ORDER BY CustomerId
