How to use materialized view in stored procedure

Question

in my stored procedure I use couple of queries (see the script below). I want to create materialized views to replace these queries. Is it possible to achieve and how to achieve it in my case? thanks in advance
set serveroutput on
DECLARE
  v_cur_tid NUMBER(5):=0;
  v_cur_cs_attendance NUMBER(5):=0;
  v_cur_c_tot_enrolments NUMBER(5):=0;
  v_most_enrolments NUMBER(5):=0;
  v_least_enrolments NUMBER(5):=0;
  v_most_pop_cid NUMBER(5):=0;
  v_least_pop_cid NUMBER(5):=0;

Hi,
you could use Dynamic SQL /Execute immediate to run DDL from a stored procedure.

Could you please tell why do you want to create a materialized view in stored procedure ?
How frequently you will runt this procedure . It would is better to create a MV once and use it.
thanks
