Creating a Job in Oracle using DBMS_JOB

问题

I'm trying to create a job that will run a certain procedure every Christmas. This is how far I have gotten:

declare
   jobno number;
begin
   dbms_job.submit( jobno,
                   'BEGIN GiveCoins; END;',
                    to_date('12/25', 'MM/DD'),
                    'sysdate + ?');
end;
/

However I can't seem to find an easy way to change the interval to yearly and am just generally quite confused about how to go about this, any help greatly appreciated

You'd want something like

declare
   jobno number;
begin
   dbms_job.submit( jobno,
                   'BEGIN GiveCoins; END;',
                    to_date('12/25/2012', 'MM/DD/YYYY'),
                    'add_months(trunc(sysdate),12)');
end;
/

This will run the job for the first time at midnight on Christmas 2012 and every 12 months after that.
