Regarding the first point, mentioned in your doc:

Quote:

In this case SQL LOADER works fine, but I have the "Prog" field empty and isn't a correct target, because I would like a sequential number
from 1 to 12000

I think it should be ok if that field is empty. After the import, you can update it with the sequence..like
update emp set empno=seq_name.nextval

and that will reset that field to sequence number.

I've imported 1 file and it's Ok, but the "Prog" field is empty I don't understand what I have to do next, could you please explain the process again?
When do I have to do the update, do I have to do it fron S.O. or SQL PLUS?

SQL > UPDATE FIREWALL SET PROG=

Sorry..I dont' understand what you mean

NiravShah suggested to make use of a database sequence.
If all you need is an incrementing unique number, use rownum.

SQL> UPDATE FIREWALL SET PROG=rownum;

That is what it does.

scott@9i > select * from dept;

    DEPTNO DNAME          LOC
---------- -------------- -------------
           ACCOUNTING     NEW YORK
           RESEARCH       DALLAS
           SALES          CHICAGO
           OPERATIONS     BOSTON


scott@9i > update dept set deptno=rownum;

4 rows updated.

scott@9i > select * from dept;

    DEPTNO DNAME          LOC
---------- -------------- -------------
         1 ACCOUNTING     NEW YORK
         2 RESEARCH       DALLAS
         3 SALES          CHICAGO
         4 OPERATIONS     BOSTON
