Hi,
Another strategy is to "backdate" the sequence!
Look at this example:SQL>select test_seq.nextval from dual;
NEXTVAL
6
SQL>alter sequence test_seq increment by -5;
Sekvens er ændret.
SQL>select test_seq.nextval from dual;
NEXTVAL
1
SQL>alter sequence test_seq increment by 1;
Sekvens er ændret.
SQL>select test_seq.nextval from dual;
NEXTVAL
2
