create materialized view my_mv
refresh fast with rowid
enable query rewrite
as
select sal_dt ,
sum(sales) sum_sales
from sales
group by sal_dt
partition by range (sal_dt)
interval (numtodsinterval(1,'day'))
(partition p_sal_dt_min values less than (to_date(' 2013-11-18 00:00:00', 'syyyy-mm-dd hh24:mi:ss', 'nls_calendar=gregorian'))
partition by range (sal_dt)
