SQL> -- MAXVALUE 999999999999999999999999999

SQL> -- So you can simplify your CREATE SEQUENCE command as follows:
SQL>
SQL> CREATE SEQUENCE mySequence
2 MINVALUE 1
3 START WITH 1
4 INCREMENT BY 1
5 CACHE 20;
Sequence created.
SQL>
SQL> select mySequence.nextval from dual;
NEXTVAL

SQL>
SQL>
SQL> drop sequence mySequence;
Sequence dropped.
