I've done exactly this for a really cheap-and-dirty instance where two people were doing bulk data entry into two different instances of a mysql table which would eventually be stitched together. by giving one a higher range, the data migration afterwords was very easy. Other than that, can't imagine a use for this approach. -P -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
