What if you know in advance what are the row that should be inserted and you've a batch of rows that should be updated? Is it still the fasted system to insert them all in a temp table with copy? What about the one that have to be updated if you've all the columns, not just the changed ones? Is it faster to delete & insert or to update? updates comes with the same pk as the destination table. thx
