But if the primary key is populated using a sequence, the chances of block split are low here. I only think of one situation with cached sequence and a lot of concurrent inserts on the table. In this case there may be block splits. But for serial inserts with a sequence block splits will not happen. Correct me if I am wrong. Received on Tue Sep 20 2005 - 05:49:41 CDT
