Querying unquoted french decimal numeric values results in ORA-00933

Question

using a french (VPC) windows XP Platform,
a french installation of the oracle database
where the locale setting are set to french,
from the clients options regionales settings, the Nobre format is set to: 123 456 789,00
the NLS_Numeric_Characters for both NLS_session_parameters and NLS_database_parameters are set to ','
when using sqlplus on the french hosts system, I find the following
select <col> from <table> where <numbercol> = 1.1
Returns a correct value
select <col> from <table> where <numbercol> = '1,1'
Returns a correct value
select <col> from <table> where <numbercol> = 1,1
returns the query error: ORA-00933: la commande SQL ne se termine pas correctement
Is this correct, are French decimal numbers always in quotes when used in a query ?

Answer 1

Perhaps this
SQL> alter session set nls_numeric_characters=',.' ;
Session altered.
SQL> select * from ( select level /2 n from dual connect by level < 10) ;
         N
        ,5
         1
       1,5
         2
       2,5
         3
       3,5
         4
       4,5
9 rows selected.
SQL> select * from ( select level /2 n from dual connect by level < 10) where n= '1,5' ;
         N
       1,5
SQL> select * from ( select level /2 n from dual connect by level < 10) where n= cast ( '1,5' as number)  ;
         N
       1,5
-- // Cannot use , for number you will have to use it as char or convert to number as in above
SQL> select * from ( select level /2 n from dual connect by level < 10) where n= 1,5
  2  /
select * from ( select level /2 n from dual connect by level < 10) where n= 1,5
