Hi Kalayan,
This query seems to be a common and easily searchable item on SCN. You can run the Report program as a background or use the standard SUBMIT REPORT functionality to get the data as SPOOL. You can leverage following link to send the data as mail.

Also, an example of using SUBMIT statement.
The SUBMIT statement executes a report from within a report - Code Gallery - SCN Wiki
Thanks,
