Question about inserting Sysdate (SQL)

Question

Hi all,
I got a question about records insert when one of the fields is sysdate.
I have to store several records representing a log, generated by the execution of a database package.
Inside my package I wrote an internal procedure devoted to insert a record in my log table for each processing step I wanted to trace (I call this proc each time I want to record a certain step of my package).
My log table structure is: PREC_LOGS(log_date DATE, log_message VARCHAR2(1000)), no constraints at all.
Database ver. 8.1.7.1.0 - Production for VMS O.S.
The 'problem' occurs when several records have the same sysdate (DD-MM-YYYY HH24:MI:SS). In this case, if I select log_date,log_message ... order by log_date, the list of records I get respects the sort condition, but when several records have the same sysdate (DD-MM-YYYY HH24:MI:SS), it doesn't respect the order of the steps theoretically inserted by the internal proc.

Please ask for more detail if someone is interested in replying...I realize it's not a very clear explanation of my issue.
Thanks, Marco

Hi
Add a field to the table that is that uses a sequence
PREC_LOGS(log_id NUMBER(30),log_date DATE, log_message VARCHAR2(1000))
Create a database sequence
The insert statement now becomes something like
INSERT INTO PREC_LOCS(log_id, log_date, log_message)
VALUES (sequence_name.NEXTVAL, SYSDATE, 'Some message');
Then order by the log_id when you do your select.
