May i know i how it will help in my case...Yes you may
just to play with something like (assuming deptno is varchar2 type as in your original post, if not, you just do to_number(substr(...)) as token and you're done
:txt should contain your department list as '10,20' or '10,30,50' ...
select *
  from emp
where deptno in (select substr(txt,
                                instr(txt,',',1,level) + 1,
                                instr(txt,',',1,level + 1) - instr(txt,',',1,level) - 1
                               ) as token
                    from (select ',' || :txt || ',' txt
                            from dual
                  connect by level <= length(:txt) - length(replace(:txt,',','')) + 1
                 )having an inline query providing the deptno list
with
inline_query as
(select listagg(to_char(deptno),',') within group (order by deptno) dept_list
   from departments
  where rownum <= :number_of_depts
select *
  from emp
where deptno in (select substr(txt,
                                instr(txt,',',1,level) + 1,
                                instr(txt,',',1,level + 1) - instr(txt,',',1,level) - 1
                               ) as token
                    from (select ',' || dept_list || ',' txt
                            from inline_query
                  connect by level <= length(dept_list) - length(replace(dept_list,',','')) + 1
                 )Regards
