You can do it in PL/SQL, it can look like this (if I understand your requirement properly):

create table sql_commands (cmd varchar2(1000));
insert into sql_commands values ('select * from table_1');
insert into sql_commands values ('select * from table_2');
commit;

declare
begin
   for aLine in (select cmd from sql_commands) loop
      execute immediate aLine.cmd into ... -- depends on your command
   end loop;
end;
