Subj:   Re: Daily updates to a history table
From:   Koduri, Harish

Just create a intermediate temporary table which contains only accounts which have accnt_class changed from account table. Define accnt_nbr as primary index for this table (i assume you have accnt_nbr as primary index on the account_class table). Then you can update the account_class table from the temp table based on the accnt_nbr which is primary index on both tables which should perform better than other options.
