Subject Select last n rows
Author guru

I'm trying to get last n rows from the query. It looks like

select degree, degree_type
from ga_degree
where degree is not NULL
order by entry_date

Lets say we have 100 rows in a table. All have different "entry_date".
I want to get "last n rows" from ga_degree.
Can not change order by clause because;
the result of a sp ( yes this is a sp ) is a string and that is :
'0056730236'. ( something like that )
Every digit represents a "degree" which was retrieved from guery.
Most left is smaller date's degree. And most right is the last degree
That why can't use "select first n ..... order by entry_date desc".

Well, with my poor English, thats all I can tell :)

Thanks for help...
