How to display S.no adjacent to employees table help plsss

Question

In a form in tabular format Emp details are displayed
Adjacent to the table i want to put a Sno display item showing
1 for 1st employee
2 for 2nd employee ......
I thought i could like create a global variable in a package specification in a program unit and assign it to 1
Package pack1 is
v_num number :=1;
end;
and then write a PRE_ITEM trigger for a Sno item in the object navigator
In the trigger
how to display the value inside v_cnt;
I tried creating a sequence
create sequence v_seq;
but the sequence really wont help me as
it would keep on incrementing
so how can i display the value inside the v_cnt in a item
Is it possible not to use a trigger and still achieve this

Answer 1

BEDE,
what will the :system.cursor_record show in a tabular block of 10 rows and what the rownum will sho instead (even if you change the where clause or the ordre by) :
- the :system.cursor_record will show the number of the fetch.
1-10 rows : 1
11-20 rows : 2 etc ...
- the rownum order by field :
rownum - field
1- A
2- B
3 - C etc..
- the rownum order by field desc :
rownum - field
1 -C
2 - B
3 - A etc..
- the rownum where clause filed != 'B':
rownum - field
1 - A
2 - C
3 - D etc..
