DBMS_SQL (NO PRIVILIGES TO CREATE TABLES)

It seems i miss some privileges to create tables with the dbms_sql package:

id1 varchar2(30);

Any answers/comments welcome
c1 integer;

nom varchar2(30);

nb_snp number;

serial2 number;

cursor c2 is select name from dba_snapshots

  where owner=3D'SCOTT'

AND NAME <> 'TEST';

return1 integer;

begin

open c2;

loop

fetch c2 into nom;

exit when c2%notfound;

dbms_output.put_line('CREATE TABLE SCOTT.' || nom || ' ('||NOM|| ' NUMBER)'); c1:=3Ddbms_sql.open_cursor;

dbms_sql.parse(c1,'CREATE TABLE SCOTT.' || nom || ' ('||NOM|| ' NUMBER)',dbms_sql.v7);

return1 :=3D dbms_sql.execute(c1);

dbms_output.put_line('RESULTAT: '||RETURN1);

dbms_sql.close_cursor(c1);

end loop;

dbms_output.put_line(SYSDATE);

dbms_output.NEW_line;

end;

execute scott.tgr_select

execute scott.tgr_select
