Are you looking for RETURNING clause..
Something like this based on the Primary Key of the table..Hope your data volume is not huge..
create or replace type num_tab as table number;
create or replace procedure p1(i_dept in number, dept_cur out sys_refcursor) is
  lt1 num_tab; 
  lt2 num_tab; 
begin
  update emp set sal=sal+100
  where deptno=i_dept
  returning empno bulk collect into lt1;
  open dept_cur for
    select ......
    from emp
    where empno in
          select COLUMN_VALUE
          from table(lt1)
end;If you need something else, pleas eexplain your exact business requirement..
