Hello guys, I am a beginner in oracle programming. Lately, I have been searching for how to make a field filled automatically, and I want this field to be a serial number.
Do I do that when creating the table, or do I have to make a function that does that for me in the form builder?
This is how I created my table :

create table Buyer_Entery_Table
(
serial_number number(6) not null ,
good_name varchar2(300),
employee_name varchar2(400),
Quantity number(6),
value number(10),
entry_number number(6),
outer_number number(6),
today date,
department_name varchar2(300),
notes varchar2(400)
);

_______________________
As you can see, the field Serial_number, I don't want the user to modify the number, at all.

Hi,

In the PRE-INSERT on Block level
declare
   v_no number;
Begin
 select xxc_no.nextval into v_no from dual;
:Block.serial_number:=v_no;
end;

and set enabled is "NO"

Why didn't you SELECT directly into :block.serial_number? Requires less typing.



Anyway, I'd rather use database trigger. It would work in all cases (not only for inserts via your Forms application). As of a SEQUENCE, yes - I agree with mist598, I'd use it too.

Hi Littlefoot, you mean create DataBase Trigger and use it in the Trigger?

Yes. If you use a DB trigger you will need to set the blocks DML Return property to Yes.

Ok,
Thank you. So, I should do the following steps:
1- create pre-insert trigger Block Level
2- the code as the following:

declare
v_no number;
Begin
select SERIAL_NUMBER.nextval into v_no from Buyer_Entery_table;
:BUYER_ENTERY_TABLE.serial_number:=v_no;
end;


Note that : Buyer_entery_table is the block name.

It is giving me errors. " You must declare SERIAL_NUMBER.nextval "

Hi you have to create Sequence on SERIAL_NUMBER(in the Database)

And the original select was from the dual table for a reason.
You run that code (assuming the sequence exists) you'll get a too_many_rows error.

The block level trigger is :
PRE-Insert
_________________________________
declare
v_no number;
Begin
select customers_seq.nextval into v_no from Dual;
:Buyer_Entery_table.serial_number := v_no;
end;

Move code from a form (i.e. PRE-INSERT you used) into a stored function; then call that function from a form.

Which is, obviously, a workaround. If you created a database trigger I suggested ages ago, you'd already have it running.

Simply create Pre Insert Trigger on Block Level and paste this code.

begin
select nvl(max(AID),0)+1 into :AID from ACCOUNTS;
end;

AID is your Database field name and :AID is filed name where you show auto number and ACCOUNTS is Database Table .

When user Commit the form ID automatically generated,

If you want to generate Auto ID when user open form then Paste code to
When new form Instance trigger.

That's it!

And if 2 sessions do it at the same time they will get the same number.
So, that's not it.

use sys.dual instead of dual, this may help you.

Was it the same exact version than OP?
Were the ORA-600 parameters same than OP's ones?

sys.dual instead of dual on block level trigger .then run the form you will get no error.

DUAL itself works just fine for me (Forms 10g connected to 10.2.0.3, running on Windows XP):

/forum/fa/12398/0/

Form runs well with DUAL as well.

Therefore, it might (but doesn't have to) be the issue in this case.
