I am using Oracle 8.1.7. I have a procedure that parses the timezone offset (from SESSIONTIMEZONE), '-05:00' for example, into a number. Please note that I first replace the colon (':') for a period ('.').
This works fine when executing the proc from Toad, SQL Plus, etc. but I get an "Invalid number" error when I call the proc from the client (a Java web service). I have output the varchar that is being parsed and it is as expected. Interestingly, the error does not occur if I use a substring of the varchar, chopping it before the period (i.e. '-05'). Can anyone explain this inconsistant behaviour?
Thank you.

Bad example. What the problem is V$session is a SYS object and requires a (sort of) direct grant to the user. The grant must be on V_$Session. Grant select on V_$session to MyUser;
Then the procedure PR_TEST_SESSION would compile.
But to the problem at hand. Could you post the procedure that parses the timezone
Thank you everyone, particularly satishkandi. I replaced the decimal with a comma in the number being parsed and it works perfectly.
-- example: fails from client
SELECT to_number ('-05.00')
INTO n_session_offset
FROM dual;
-- example: works
SELECT to_number ('-05,00')
INTO n_session_offset
FROM dual;
Is it possible to dynamically get the decimal place separator from Oracle based on the client settings?

SQL and PL/SQL engines use different parsers. for eaxmple you can use V$SESSION inside a sql statement. But you can't do it directly through a procedure,
select * from V$SESSION where program = 'TOAD.exe'
and rownum < 2
1 row selected.
declare
n number;
begin
select sid into n from V$SESSION where program = 'TOAD.exe'
and rownum < 2;
dbms_output.put_line('N = '||n);
end;
N = 11
create or replace procedure PR_TEST_SESSION is
n number;
begin
select sid into n from V$SESSION where program = 'TOAD.exe'
and rownum < 2;
dbms_output.put_line('N = '||n);
end;
Warning: Procedure created with compilation errors
show error
PLS-00201: identifier 'SYS.V_$SESSION' must be declared
So it may happen. Can you post the query and it's result from SQL*PLUS. So that we can think of some alternatives/work-around.
