   return varchar2
   is
   v_var varchar2(30):='0.00|0.00';
begin
   begin

                           group by lbrcode,mainacctid
                   exception
                   when no_data_found then
                   return v_var;
   end;
           return v_var;
end t_recovery;when i created above function oracle did not show any error
but when i tried the function
SQL> SELECT LBRCODE,PRDACCTID,T_RECOVERY(LBRCODE,PRDACCTID,TO_DATE('31-OCT-2011','DD-MON-YYYY')) REC FROM D009022
  2  WHERE LBRCODE=18;
SELECT LBRCODE,PRDACCTID,T_RECOVERY(LBRCODE,PRDACCTID,TO_DATE('31-OCT-2011','DD-MON-YYYY')) REC FROM ac_mastfolllowing error ocurred

Answer 1

See examples in the link provided:
The Format Model of the to_char function uses the letters D and G as the decimal and the group separator respectively to be able to cope with different languages.
