Don't you think that relying on (a) rowid being consecutive (b) rowid order being identical to date order is just a little bit dodgy? What if the table has been created by a bulk load, not necessarily in ascending date order? What if some rows have been deleted? _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
