Separating character and number within the string

Question

I want to separate the character and the number within one string.
For example,
12345ABCD (the numbers and character may differ in lengths)
I want to separate into two different string of 12435 and ABCD.
Your help would be greatly appreciated.
Thanks!

Answer 1

here is an example:
sample_separator.sql
declare
  i        number := 0;
  j        number := 0;
  x        number := 0;
  vBasis   Varchar2(40) := '12345ABCD';
  vString1 Varchar2(40);
  vString2 Varchar2(40);
begin
  for x in 1 .. length(vBasis) loop
    for i in 0 .. 9 loop
      if substr(vBasis,x,1) = to_char(i) then     
        vString1 := vString1 || substr(vBasis,x,1);
      end if;
    end loop;
    for j in 65 .. 90 loop
      if substr(vBasis,x,1) = chr(j) then
        vString2 := vString2 || substr(vBasis,x,1);
      end if;
    end loop;   
  end loop;
  dbms_output.put_line('vString1: '||vString1);
  dbms_output.put_line('vString2: '||vString2);
end;
/when run:
SQL> @r:\sample_separator.sql;
vString1: 12345
vString2: ABCD
