Variable as table

Question

I have to join one view about 15 times in my procedure. This view is so heavy, select * from it takes ab 5 seconds.
Is there any posibility to use this view as variable in SQL? Maybe same others ideas how to make it faster?
For Example:
tmp_table = select pk_id1, pk_id2, name, date from heawyView;
select count(*) from mainTable a
join tmp_table b on (a.pk_id1 = b.pk_id1 and a.pk_id2 = b.pk_id2);

My bad. Bulk collect should be:
SELECT  view_obj_type(col1,col2,...)
  BULK COLLECT
  INTO v_view_tbl
  FROM  view;For example:
SQL> CREATE OR REPLACE
  2    TYPE emp_obj_type
  3      AS OBJECT(
  4                empno number,
  5                ename varchar2(30),
  6                deptno number
  7               )
  8  /
Type created.
SQL> CREATE OR REPLACE
  2    TYPE emp_tbl_type
  3      AS TABLE OF emp_obj_type
  4  /
Type created.
SQL> SET SERVEROUTPUT ON
SQL> DECLARE
  2      v_emp_tbl emp_tbl_type;
  3  BEGIN
  4      SELECT  emp_obj_type(empno,ename,deptno)
  5        BULK COLLECT
  6        INTO  v_emp_tbl
  7        FROM  emp;
  8      FOR v_rec IN (SELECT e.*,d.dname FROM dept d JOIN TABLE(v_emp_tbl) e ON(d.deptno = e.deptno)) LOOP
  9        DBMS_OUTPUT.PUT_LINE(RPAD(v_rec.ename,30) || v_rec.dname);
10      END LOOP;
11  END;
