Reset a sequence

Question

Hi,
This is the requirement. WE have a code which creates an outbound file containing the posted journal entries. These are named in a way that there is a sequence at the end of the name.
We need to reset the sequence used in that code every month so that it starts from one at the beg. of the month.
Any help is appreciated.
Thanks,
Ash

possible solutions:
1. create a procedure that drop and create the sequence dynamically
       create or replace procedure prc_recreate_sequence(pSeqName varchar2, pStartNum Number, pIncrementNum Number) as
       begin
          execute immediate 'Drop Sequence '||pSeqName;
          execute immediate 'Create Sequence '||pSeqName||' Start With '||pStartNum||' Increment By '||pIncrementNum;
       end;
       /2. create a table that logs the current value as a sequence bypassing the use of the actual sequence
       create table sequence_log
         (sequence_name  varchar2(40),
          start_with     number,
          increment_by   number,
          current_val    number);
       insert into sequence_log
       values ('trans_dtl_seq',1,1,1);in your code call this table to utilize it
       declare
         vSeqNum     number := 0;
       begin
         select (current_val)+1
           into vSeqNum
           from sequence_log
          where sequence_name = 'trans_dtl_seq';
         update sequence_log
            set current_val = vSeqNum
          where sequence_name = 'trans_dtl_seq';
        end;
