Come invertire una stringa (SQL Server 2005, SET BASED)

Modifica La risposta originale ha frainteso il requisito. Ho preparato una soluzione, ma ora la suddivisione a livello del personaggio non è del tutto necessaria. Almeno potrebbe dare qualche spunto!

WITH Strings AS
(
select 'A Student' as String
UNION ALL
select 'blah' as String
UNION ALL
select 'the quick brown fox jumped over the lazy dog' as String
),
SplitChars As
(
SELECT ROW_NUMBER() OVER (ORDER BY number) AS number, String, SUBSTRING(String,number,1) AS Ch FROM Strings
JOIN master.dbo.spt_values on number BETWEEN 1 AND LEN(String) AND type='P'
)


SELECT String,
replace(Stuff(
            (
            Select '' + Ch
            From SplitChars SC3
            WHERE SC3.String = SC.String
            Order By (SELECT COUNT(*) FROM SplitChars SC2 WHERE SC2.String = SC3.String AND SC2.Ch = ' ' AND SC2.number < SC3.number) desc, case when SC3.ch = ' ' then -1 else number end
            For Xml Path('')
            ),1, 0, ''), '&#x20;', ' ') AS Reversed
FROM SplitChars SC 
GROUP BY String
