Did you use 'recycle'?
Sequence must not use 'cache' when attempting to do this.

You may also want to check out other options from the Google link posted by Raj.

Kirti,

I have to set the maxvalue manually, when I do this still nextval not reset. For example if the maxvalue is 1000000 and the current value is 500, some how I have to set alter sequence to reach the maxvalue so the next value start from 0 again.
This test doesn't do that.

Hamid,

Here is one way:

SQL> select myseq.currval from dual;

   CURRVAL

---

         4

SQL> alter sequence myseq nocache;

Sequence altered.

SQL> alter sequence myseq maxvalue 4 cycle;

Sequence altered.

SQL> select myseq.nextval from dual;

   NEXTVAL

---

         1

SQL> REM ---> Other alter sequence commands to change maxvalue, cache, nocycle etc.                

Now, you get to do the tricky part of automating it ;) Because, I have not attempted to do it, yet.

HTH,
