Hi,

I know this I'm about to say won't help much, but it seems to me that the 
mechanism being searched
by the original posteris something provided by Active Data Objects (ADO). In 
ADO you can specificy
the dimension of a page of records and then you can ask for a specific page 
within the recordset
returned by the original query. I am not aware of the cost of this mechanism 
on the server, because
its obvious that at some point the required work (finding the total number of 
records, finding and
retrieving the records for the selected page) will have to be done. But it 
sure eases the life of
the programmer.
Unfortunately in Unix or Linux the only way you could use this would be 
through an ASP plataform
such as Chili!ASP or something similar.

It sure would be nice to have this in freetds, but it would be quite a move 
from the current
philosophy.

Regards

Rui Ribeiro
