ORA-01890 NLS error detected

Question

Hello,
I have an NLS error message while trying to get a series of sequences. My sequence seems to work fine, but when I try to get multiple sequences at on time, I have the following message:
SQL> select next_location_id from dual;
NEXT_LOCATION_ID
200001608
SQL> select next_location_id, next_location_id from dual;
select next_location_id, next_location_id from dual
ERROR at line 1:
ORA-01890: NLS error detected
ORA-06512: at "CODBA.NEXT_LOCATION_ID", line 4
ORA-06512: at line 1I have looked into the ORACLE error message documentation, but it does not help me.
ORA-01890 NLS error detected
Cause: An NLS error was detected.
Action: Look for additional error messages and take appropriate action. If there are no additional errors, call Oracle Customer Support.
The procedure I used is very simple:
create or replace function NEXT_LOCATION_ID return number as
l_retour number(9);
begin
if to_char(sysdate, 'YYYY') = '2002' then
select location_id_2002.nextval into l_retour from dual;
elsif to_char(sysdate, 'YYYY') = '2003' then
select location_id_2003.nextval into l_retour from dual;
elsif to_char(sysdate, 'YYYY') = '2004' then
select location_id_2004.nextval into l_retour from dual;
elsif to_char(sysdate, 'YYYY') = '2005' then
select location_id_2005.nextval into l_retour from dual;
else
l_retour := -1;
end if;
return (l_retour);
end;
We have the same problhme when we used directly the sequence.
Someboby can help me??

This type of error is difficult to debug. It might have to do with how the NLS_DATE_FORMAT was set up,
since you are using sysdate in your function.
Does it work if you do the following?
select location_id_2002.nextval, location_id_2002.nextval from dual;
