if you're using asp, you might want to have a look at


and i'm pretty usre there's plenty of stuff on learnasp.com and
4guysfromrolla.com on recordset paging.  one of the methods at adopenstatic
is to use a stored proc to only return the results that you want...which is
great if you have, for example, a searchable archive of a mailing list and
you want to return 20 messages along with their associated threads, which
means there could be any number of records actually being returned.

iirc, when you do recordset paging in asp+ado you don't get all the results
everytime, only the chunk that you need.  this is set up by the size that
you set your recordset cache for before you run the query and the database
*should* only be hit again when you want data that isn't in you cache.

that said, if the cache is bigger than the number of records being shon on
the page in one go, you need some way of persisting the data between pages.

anyway, the last time i had to do this was a good while ago and it always
seemed to return all the records on the first hit...but ymmv! :>
