Partition error

Question

I want to create a partition for a table on a before insert trigger of the same table.
create or replace trigger eventlog_trg
before insert on eventlog
for each row
declare
pramga autonomous_transaction
begin
alter table eventlog add partition .....
commit;
end;
when i insert into eventlog values (....)
it gives a error ora 14400 - inserted partition key does not map to any partition.
After checking with dba_users_partitions,i found that the partition is created,and it happens only for first time insert
though the first insert gives this error , on subsequent insert into the table for same partition key,it is sucessfully inserted .
please help.

For dynamic partition creation you need to upgrade your database to Oracle 11g.
The behavior you are experiencing is an expected one. At the time the INSERT statement was fired there was no such partition and hence the insert is failing.
