Would you know if the common practice of generating a separate sequence number for each table as primary key is the best practice under this scenario? To do it this way, I see that 2 more columns need to be added to the tables (1 for 'buyers' table and 1 for 'sellers' table, for example) as their foreign keys that contain the same value as the primary key in table 'users'? This would free these tables to have their own independent sequence values as primary keys. Thanks. Received on Mon Jun 15 2009 - 11:51:53 CDT
