I really appreciate you for your answer thanks. And the output was the same as i was thinking.

Since i am a newbie , i am having some problem while trying to understand your code.

Following are the area which are new to me i would really appreciate if you could spare some time and help me with them. Either you can provide some link or you can explain them.

SELECT (SELECT N

FROM (SELECT TOP (LEN(@number))

SUBSTRING(CAST(@number AS VARCHAR(19)),N,1)

FROM (VALUES(1),(2),(3),(4),(5),(6),(7),(8),(9),

(10),(11),(12),(13),(14),(15),(16),(17),

(18),(19))a(N)

WHERE N <= (LEN(@number))

ORDER BY N DESC) b(N)

FOR XML PATH(''), TYPE).value('.', 'VARCHAR(19)');

In the above example we have not define the variable 'a' , 'b' & 'N' and then also we are using it.

Please help me out with the above question.
