If I have a lot of data which updates/inserts an existing table but I
don't know if a given record will be an update or an insert, then I
write all the 'new' data to a temporary table and then use sql
statements to achieve the updates and inserts on the existing table.

Is there a better way of doing this in standard SQL?
