Divisor is equal to zero in date function

Question

Hi
I have used a query like this but am getting error like divisor is equal to zero
with s_mon as (select to_char(add_months(trunc(sysdate,'rr'),level-1),'Mon-RR') month from dual connect by level <=12)
select s_mon.month,
tgdate
from abc ,s_mon
where to_char(tgdate(+),'Mon-RR')=s_mon.month
Result should be like this
month tgtdate
jan-12 01-01-12
feb-12 05-02-12
mar-12
apr-12
dec-12

Vishnu,
I did not get any error for the below statements; Does this not match with yours? If not, then please post your table structure, data and the exact query in which you are facing error.
drop table test_table;
create table test_table (pk_col number, col date);
insert into Test_table values (3, to_date('MAY-2012', 'MON-RR'));
insert into Test_table values (4, to_date('DEC-2012', 'MON-RR'));
select * from test_table;
with t as
  select to_char(add_months(trunc(sysdate, 'rr'), level - 1), 'MON-RR') month
    from dual
  connect by level <= 12
select b.month, a.col
  from test_table a,
       t b
where to_char(a.col(+), 'MON-RR') = b.month
MONTH     COL
APR-12     
AUG-12     
DEC-12     01-DEC-12
FEB-12     
JAN-12     
JUL-12     
JUN-12     
MAR-12     
MAY-12     01-MAY-12
