Help in dbms_job.submit

Question

Hi All,
DECLARE
  ln_jobno NUMBER;
BEGIN
  -- To run at 11:00 each day
  dbms_job.submit(ln_jobno,
                  'dwsp_ext_lyris(''' || to_char(trunc(sysdate - 1),'DD-MON-YYYY') || ''',null);',
                  to_date('11-JUL-2011 11:20', 'DD-MON-YYYY HH24:MI'),
                  '(trunc(sysdate) + 1) + (11/24)');
  COMMIT;
END;
/The Job created successfully and running too.
But the procedure 'dwsp_ext_lyris' takes two argument of which one is date and the everyday the date passing to the procedure must be incremented by one
Say for today it should look like 'dwsp_ext_lyris('11-JUL-2011',null);
But this is not happening as I created this yesterday my dba_jobs table has o/p like this.
SQL> select t.JOB,t.LAST_DATE,t.NEXT_DATE,t.BROKEN,t.interval,t.WHAT from dba_jobs t where t.JOB = 797192;
       JOB LAST_DATE   NEXT_DATE   BROKEN INTERVAL                                                                         WHAT
    797192 11/07/2011  12/07/2011  N      (trunc(sysdate) + 1) + (11/24)                                                   dwsp_ext_lyris('10-JUL-2011',null);
SQL> I want dwsp_ext_lyris('10-JUL-2011',null); to be incremeted daily.
can anybody help how should I pass sysdate - 1 to procedure everyday.

Hello
I think you just have your quotes in the wrong place. You need the procedure to evaluate the expression, not the call to DBMS_JOB....
DECLARE
  ln_jobno NUMBER;
BEGIN
  -- To run at 11:00 each day
  dbms_job.submit(ln_jobno,
                  'dwsp_ext_lyris(to_char(trunc(sysdate - 1),''DD-MON-YYYY''),null);',
                  to_date('11-JUL-2011 11:20', 'DD-MON-YYYY HH24:MI'),
                  '(trunc(sysdate) + 1) + (11/24)');
  COMMIT;
END;
/ However, you should really try to pass dates as dates, not strings. If the data type of the parameter to dwsp_ext_lyris i actually a date, you can just use...
DECLARE
  ln_jobno NUMBER;
BEGIN
  -- To run at 11:00 each day
  dbms_job.submit(ln_jobno,
                  'dwsp_ext_lyris(trunc(sysdate - 1),null);',
                  to_date('11-JUL-2011 11:20', 'DD-MON-YYYY HH24:MI'),
                  '(trunc(sysdate) + 1) + (11/24)');
  COMMIT;
END;
