Function in a Trigger

Question

Hello every one. I have a question for you. I need a second eye, I think I am missing something. OK I have the following trigger
1 CREATE OR REPLACE TRIGGER lock_ids_autonumber
2 BEFORE INSERT ON lock_ids FOR EACH ROW
3 BEGIN
4 IF :NEW.id IS NULL THEN
5 SELECT column_value as seqnum from table(ome_nextval(upper('lock_seq'))) INTO :NEW.id FROM dual;
6 END IF;
7* END;
Where ome_nextval is a function, it is as following. The function returns the type which is CREATE TYPE num_t AS TABLE OF NUMBER
CREATE OR REPLACE FUNCTION ome_nextval(p_seq_name IN VARCHAR2,
p_block_size IN NUMBER DEFAULT 1)
RETURN num_t
PIPELINED AS
PRAGMA autonomous_transaction;
pl_current_value NUMBER := 0;
BEGIN
SELECT current_value
INTO pl_current_value
FROM my_sequences
WHERE seq_name = p_seq_name
FOR UPDATE OF current_value;
UPDATE my_sequences
SET current_value = current_value + p_block_size
WHERE seq_name = p_seq_name;
COMMIT;
FOR i IN pl_current_value..pl_current_value+p_block_size - 1
LOOP
PIPE ROW(i);
END LOOP;
END;
When I run the trigger, I get the folloiwng error...
LINE/COL
ERROR
2/8
PLS-00049: bad bind variable 'NEW.ID'
3/9
PL/SQL: SQL Statement ignored
3/93
PL/SQL: ORA-00933: SQL command not properly ended
LINE/COL
ERROR
3/98
PLS-00049: bad bind variable 'NEW.ID'
I will really appreciate it, if some one can point to the mistake I am making.

Hi Alex,
That would probably be due to this thread:
Re: Sequence Issue
If you take a holiday in San Francisco, you should first read up, before posting again ;-)
(and have some coffee ofcourse).
Now, I totally agree of course: the block-allocate solution I offered, was never meant to be used for block sizes of 1...
