I have a large historical transaction table (15-20 million rows MANY columns) and a table with one row one column. The table with one row contains a date (last processing date) which will be used to pull the data in the trasaction table ('process_date').

Question: Should I inner join the 'process_date' table to the transaction table or the transaction table to the 'process_date' table?
