Autonumber

Hi,

I have an Oracle table created. The field 'SourceID' which is now a number field in Oracle used to the Primary Key in Access.

Now, I fished thru the forums to get this answer and the only thing that I found was use a sequence and a trigger, which I have no idea how to do.

So, could somebody point me in the right direction by either sending some code (currently i do all adding, updating, etc from my local machine sql statements) and direct some docs.

Thanks in advance.

Code:

---

SQL> create table xyz (id number(10), data varchar2(10));
Table created.

SQL> create sequence autonum ;
Sequence created.
SQL> select autonum.nextval from dual;

  NEXTVAL
----------
        1

SQL>  (OK, I skipped a couple steps here while I debugged my trigger.  The result is below)
SQL> edit
Wrote file afiedt.buf

  1  create or replace trigger xyz_bi before insert on xyz
  2  for each row
  3  begin
  4    select autonum.nextval into :new.id from dual;
  5* end;
SQL> /

Trigger created.

SQL> desc xyz
 Name                                      Null?    Type
 ----------------------------------------- -------- ------------------
 ID                                                NUMBER(10)
 DATA                                              VARCHAR2(10)

SQL> insert into xyz (data) values ('Z');

1 row created.

SQL> insert into xyz (data) values ('Y');

1 row created.

SQL> insert into xyz (data) values ('X');

1 row created.

SQL> commit;

Commit complete.

SQL> select * from xyz;

        ID DATA
---------- ----------
        2 Z
        3 Y
        4 X
