What are you doing in "(necessary filters)"? The only thing that comes
to mind is that if you are doing some kind of result limiting (like
MySQL's LIMIT clause), then the database might be incorrectly using
the table's stored sum in the system catelog. But, if you're offering
it a date range in the WHERE clause, etc., it shouldn't be using that
stored value.

Still, aside from serious deviation in Sybase from SQl standard, I
don't see us being able to help without seeing the WHERE clause.
