Help me to solve the problem while Uploading

Question

Hi Everyone,
I am importing datas from spread sheet to database table by APEX upload.
In my case the client made thier entries in Spread sheet,I have to upload their entries in to Database table.Our client does not know the value for primary column and also he need not know the primary id value.In such a instance how can I assign a sequence value to particular column(primary key column) apart from spread sheet.
Thanks in advance

I actually meant that you must create a new table from the spread sheet, not a new application.
Do you want to load it from your application every time?
If you do not need to load it from your application every time, do what I recommended. After you have created the new table, the sequence will be created and the trigger is automatically created. Then you can just load the spread sheet in every time (without the primary key) - it will be created from the sequence.
You can even try it from the application after you have created it the first time.
OR
You can try this:
1) Create a sequence that must start from the last value that you had (or you can use an existing sequence if you have one).
2) Create a trigger on your table with the following:
create or replace trigger "bi_ORGUNITS" -- bi_orgunits is the name of trigger
before insert on "ORGUNITS" -- orgunits is the name of your table
for each row
begin
if :new."ID" is null then
select "ORGUNITS_SEQ".nextval into :new."ID" from dual;
-- Orgunits_seq is name of your sequence and ID is name of your primary key
end if;
end;
Please let me know if you got it right.
