You could update based on key value. If the key = 11 now, then setll for
the key -10 and update that record, then add 10 to it, something like
that.

As a rule inherent in the database, I am not sure. Interesting question.

Subject: log file

Is there something I can do to a file to cause it to keep the last <= n
records added to it? That is, if n is 10, writing the 11th record would
cause record 1 to be discarded, and the new record would be the 10th
record in the file.

Something like that would be useful in the case of a log file. The file
is
helpful for diagnosing recent problems, but you don't want it filling up
the disk, or filling up and being unable to write more records.
