Convert DD-MON-YYYY format to MM/DD/YYYY

Question

I have an input date variable L_DATE as 11-Aug-2013(DD-MON-YYYY).
In my procedure, I am converting the input date to MM/DD/YYYY format .
The logic I have used for the same in my Stored Proc- COMPARE2 is:
R_DATE := to_char(to_date(L_DATE,'DD-MON-YYYY'),'MM/DD/YYYY');
But this is the error that I get when the SP is run:
ORA-01843: not a valid month
ORA-06512: at "COMPARE2", line 51
ORA-06512: at line 2
Can anyone suggest how to resolve this??

Answer 1

Input data doesnt match NLS_DATE_LANGUAGE setting
Consider
select * from v$nls_parameters
where
parameter ='NLS_DATE_LANGUAGE'
PARAMETER VALUE
NLS_DATE_LANGUAGE AMERICAN
select
to_char(to_date('11-MAY-2013','DD-MON-YYYY'),'MM/DD/YYYY') d
from dual
D
05/11/2013
select
to_char(to_date('11-MAY-2013','DD-MON-YYYY','NLS_DATE_LANGUAGE=GERMAN'),'MM/DD/YYYY') d
from dual
ORA-01843: not a valid month
or
The month is not given literally
select
to_char(to_date('11-05-2013','DD-MON-YYYY'),'MM/DD/YYYY') d
from dual
ORA-01843: not a valid month
