how to add multiple parameters in data set for BIRT report

how to add multiple para开发者_开发问答meters in data set for BIRT report ,till now i am able to add only one parameter. my sql query for datset is

select cid,attdate,intime,outtime

from att_emp_swipe where attdate >= ?

Just use multiple ?-s.

select cid,attdate,intime,outtime
from att_emp_swipe where attdate >= ? 
and something_else = ?

Data set parameters are bound in order of ? apperance.
