Imagine this:

create table whatever (
   pk_column bigint not null ,
   other_stuff char(100),
   ...
);
commit;

alter table whatever
add constraint pk_whatever
primary key (pk_column);
commit;

Insert into whatever (pk_column, other_stuff)
values (667, 'The neighbour of the beast!');

commit;

In this example, the pk_column will be set to whatever value is passed 
to the INSERT statement and need not start at zero or one.

If, as is possible, you are using a sequence to generate the values - 
say via a trigger, then you simply set the sequence value to the desired 
starting number.

So, if you used a sequence named seq_pk_whatever, you could - before 
using it for the first time - execute the following to ensure that the 
next value generated will be 667:


set generator seq_pk_whatever to 666;
