You need to do in manually...
Create or replace view all_data as
(select * from data_2000
union all
select * from data_1999
union all
select * from data_1998)
Be sure to use the union all, not union as there is quite a big performance difference and different result set. Simply drop unwanted partition, create a new one and then recreate the view.
Of course your primary key values aren't maintained across the tables so you could have duplicates if you let them slip through your logic.
This is a tried and tested way of manually partitioning in 7.x
