AFAIK views cannot accept parameters. Instead you can either use a store procedure or a function which can accept parameters.

You can always use where clause to filter out the data. That is as good as a paramater.
Partitioned view requires that you have check constraint on each table of view.
create table SalesTill1999 ( Year int CHECK (Year < 1999 ) , .... )
create table Sales1999 ( Year int CHECK (Year = 1999 ) , .... )
create table Sales2000( Year int CHECK (Year = 2000) , .... )
create table Sales2001 ( Year int CHECK (Year = 2001) , .... )
then you create a view based on this 4 tables.
create view Sales as select * from SalesTill1999 union select * from Sales1999 union select * from Sales2000 union select * from Sales2001
evry time a qry refering to particular year is fired against this view, SQL will only use the necessary table only. Others will not be accessed.
e.g. select * from Sales where year = 2000 will only access Sales2000 table.
