How do you specify IN clause in a dynamic query using a variable?

Question

In PL/SQL, you can specify the values for the IN operator using concatenation:

v_sql := \'select field1
from table1
where field2 in (\' || v_list || \')\';
<

Like in @Sathya link, you can bind the varray (I took @Codo example):

CREATE OR REPLACE TYPE str_tab_type IS VARRAY(10) OF VARCHAR2(200);
/
DECLARE
  l_str_tab str_tab_type;
  l_count NUMBER;
  v_sql varchar2(3000);
BEGIN
  l_str_tab := str_tab_type();
  l_str_tab.extend(2);
  l_str_tab(1) := 'TABLE';
  l_str_tab(2) := 'INDEX';

  v_sql := 'SELECT COUNT(*) FROM all_objects WHERE object_type IN (SELECT COLUMN_VALUE FROM TABLE(:v_list))';

  execute immediate v_sql into l_count using l_str_tab;

  dbms_output.put_line(l_count);
END;
/

UPDATE: the first command can be replaced with:

CREATE OR REPLACE TYPE str_tab_type IS TABLE OF VARCHAR2(200);
    /

then call:

l_str_tab.extend(1);

when ever you add a value
