Nice trick Joe !!!

  NO, you dont need to DROP the sequence, here is demo code i used to reset a sequence(this resets it back to 1).

  SQL> drop sequence test_seq;

  Sequence dropped.

  SQL> create sequence test_seq;

  Sequence created.

  SQL>
  SQL> declare
    2 seq_hold_var number;
    3 begin
    4 for i in 1 .. 100000 loop
    5 select test_seq.nextval into seq_hold_var from dual;     6 end loop;
    7 end;
    8 /

  PL/SQL procedure successfully completed.

  SQL>
  SQL> select test_seq.nextval from dual;

     NEXTVAL                                                                      
  ----------                                                                      
      100001                                                                      

  SQL>
  SQL> alter sequence test_seq increment by -100000;

  Sequence altered.

  SQL>
  SQL> select test_seq.nextval from dual;

     NEXTVAL                                                                      
  ----------                                                                      
           1
