Performanace Issue

I have worked in a table with one timestamp field namely Actiondate. We have updated the sysdate value of inserting time to that field. It contains around 30 lakhs records.

I want to get the records which are inserted a particular day.

I run the following 2 queries..

select * from history
where trunc(actiondate) > trunc(sysdate)
order by docintno

OR

select * from history
where trunc(actiondate) > '01-dec-2009'
order by docintno

Both are taking too much time to give the results.
