Tuning of very small procedure

Question

Hi All,
We are using the following procedure to get respective sequence number by passing the table name as parameter:
================================
CREATE OR REPLACE procedure SEQ_GEN(Tbl_name in varchar2, SEQ_NO out number) is
seq_name varchar2(100);
select_str varchar2(100);
BEGIN
seq_name:= tbl_name||'_seq';
select_str := 'select '||v_seq_name||'.nextval from dual';
execute immediate v_select_str into seq_no;
EXCEPTION
WHEN OTHERS THEN
-- If Sequence does not exists in the database
IF (SQLCODE='-002289') THEN
Dbms_Output.PUT_LINE('This sequence does not exist: '||v_seq_name);
end if;
END seq_gen;
========================
Daily, millions of records will be loaded using this procedure.
(An ETL Tool will be calling this procedure)
Is there any way this procedure can be fine tuned?
Awaiting your inputs
Thanks,
Kishore

Will it improve the performance if created as
function instead of proc?You are loosing the point. Whatever you do will never improve the performance as you don't need this procedure.
First, let my mind clear on the idea:
Can't you really directly use seq.nextval?
We have taken care so that all the sequences are
present in db.Yes, db already takes care, so returns the error: "object does not exists". If you don't have the sequence present, you cannot do what you want, anyway. Displaying the error manually doesn't fix the situation.
