Answer 1

you have to create a database procedure to execute your statement.
Then create a job in sql*plus like this:
variable sqlplus_jobno number;
declare
cursor get_cur_jobno is
select uj.job
from   user_jobs uj
where what = lower ( 'your_procedure_name' );
begin
open  get_cur_jobno;
fetch get_cur_jobno into :sqlplus_jobno;
close get_cur_jobno;
if
  :sqlplus_jobno is not null
then
  dbms_job.remove ( :sqlplus_jobno );
end if;
dbms_job.submit ( :sqlplus_jobno,
                  'your_procedure_name;',
                  sysdate,
                  'trunc ( sysdate, ''hh24'' ) + (1)', false );
end;
commit;
print sqlplus_jobno This will execute your procedure every day at midnight and onetime immediatly.
To wake up the the job process in your database, you have to look on two
system parameters called job_queue_processes and job_queue_interval .
set job_queue_processes to minimum 1 (one process is started)
and job_queue_interval to 60 (check every minute for a job)
