I wanna to Assign A sequence numbers to an item in a
Form , i tried by this method : [/align



I create a pre-insert trigger and i wrote this query

Select s_ord_id.nextval
into :s_ord.id
from dual

then i wrote this INSERT Statement
insert into Order

[align=left]Values(:s_ord.id,.............)

But it Didn't work so what is the problem is it the trigger type or what?

I don't wanna to make it by the Initial VALUE method


Waiting from u As Fast As U can

تستطيع عمل داله تقوم بعمل ذلك

FUNCTION get_emp_id RETURN number IS
v_id number;
BEGIN
select std_id_seq.nextval
into v_id
from dual;
return v_id;
END;

وتقوم بعمل trigger من نوع pre-insert يقوم بجعل قيمة الحقل مساوية للقيمة التى ترجعها هذه الدالة

:emp.empno := get_emp_id()
