select *,
(select sum(planmoney) as pl from table as inn where project_id = table.project_id and inn.date <= table.date) as plan_total,
(select sum(actualmoney) as act from table as inn where project_id = table.project_id and inn.date <= table.date) as act_total
 from table  order  by project_name,date;
