-----Original Message----- Sent: Thursday, March 07, 2002 9:13 AM To: Multiple recipients of list ORACLE-L HI, We have some history tables that are pointing to parent tables. Parent tables has primary key. Our developers are saying that we have foreign key from history table to parent table and we don't need primary key on history table. Does there are any benefits if we have primary key(concatenated) on history table. OR do we should leave history tables without primary key Thanks --Harvinder -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Harvinder Singh INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
