Could you start using negative numbers in your column, or would that throw all your applications out of whack? E.g. alter sequence ... minvalue -999999 ; -----Original Message----- Knight, Jon We have a sequence that is about to reach it's maximum value (999999). Ordinarly, I would just expand the column and let it keep going, but it populates a business column. They don't care what the value is, as long as it's unique and no longer than 6 digits. Of course, like many sequence populated columns, it's not consecutive. -- http://www.freelists.org/webpage/oracle-l
