I do not think Oracle will design it this way. If it's me who put the design I will validate normally during any DML and mark the records that do not satify the constraint to be checked at a later stage (commit time).
Regards, Waleed -----Original Message----- To: Multiple recipients of list ORACLE-L Sent: 4/4/02 6:53 AM Hi all, When testing behaviour of INITIALLY DEFERRED foreign key constraints I'm confused by the following behaviour and I'd appreciate any interpretation! I create the FK constraint on a column in a 1 million row table. This works OK - if I update individual entries to nonsense values, there is no error until I try to commit. So far so good. However, if I do an UPDATE which affects all rows, and then commit, the commit returns immediately (provided the UPDATE is to correct values, not nonsense). Why is there no delay whilst validating the million rows? (Certainly it takes several seconds to create the constraint in the first place). Any insight welcome!
