Auto-increment in Oracle without using a trigger

Question

What are the other ways of achieving auto-increment in oracle other than use of triggers?

Answer 1

Create a sequence:

create sequence seq;

Then to add a value

insert into table (id, other1, other2)
values (seq.nextval, 'hello', 'world');

Note: Look for oracle docs for more options about sequences (start value, increment, ...)
