Hi,

This may not work because Oracle can insert records into empty space in the datafile rather than at the end of the datafile. Remember that RDBMS theory states that the order in which data is stored and retrieved is arbitrary and that any ordering of the data is derived from indexes, not from the sequence in which the data was stored.

If you want the ten most recent adds you could add a sequence column and then use the sequence as the basis for your query.

Jerry Gitomer
