if count(rows) = 500
then delete the first row

Hi,
I would like to implement a log table with a finite dimension, for exemple a
table with 500 records, and when the last record is set in the table I would
like to come back at the first tuplet and write over the previous value
recorded. I think it's the way SQLite journal is implmented.
Is there any way to declare this table with these properties included, so I
don't have to add code to do this function?
Thanks
Julien
