Hi,

Use the below Oracle function..

create or replace function remove_special_chars (i_input varchar2)
return varchar as
l_temp varchar2(100);
o_output varchar2(100);
i number;
begin
for i in 1..length(i_input)
loop
select substr(i_input,i,1) into l_temp from dual;
if ascii(l_temp) >= 32 or ascii(l_temp) <= 126 then
o_output := o_output || l_temp;
end if;
end loop;
return o_output;
end remove_special_chars;
/

Thanks,
Ravindran
