Depends on what you need really. You can make sequences cycle. Otherwise (if you need to reset everyday for instance) either you drop and recreate (which means that you will have to reset grants), or you can cheat as follows :
1) You alter the sequence, setting its maxvalue to current value and setting it to CYCLE. I think that setting CACHE to 1 could be wise too. 2) You get nextval
3) You alter the sequence back.
