Number - string question

Question

Hello,
I have the next problem:
I have cursor that contains the next thing:
WHERE LKP_INDUSTRY1_ID IN ( p_sector )
p_sector is being delivered in varchar: '23;22;36'
My question is: is it possible to manipulate p_sector in a way that I can paste it in my cursor? I can replace the ';' with ',' but I don't know how I can make it read the numbers as numbers and not as strings.
Thanks in advance.
Oli

Does this solve your problem ?
SQL> create or replace type tab_n is table of number;
  2  /
Type created.
SQL> declare
  2   p_sector varchar2(20) := '7369;7499;7521';
  3   t tab_n := tab_n();
  4   element number;
  5   pos integer := 0;
  6   cursor a is select ename from emp where empno in (select * from table(t));
  7  begin
  8   for i in 1..length(translate(p_sector || ';',';0123456789',';')) loop
  9    t.extend;
10    t(t.count) := substr(p_sector,pos+1,instr(p_sector || ';',';',1,i)-pos-1);
11    pos := instr(p_sector,';',1,i);
12   end loop;
13   for v in a loop
14    dbms_output.put_line(v.ename);
15   end loop;
16  end;
