At the risk of looking foolish (again)

If I read this correctly, the tables are 100% identical except for the datetime field???

If so it doesn't matter which table the record comes from (since they're identical). You just need to get a record and the latest timestamp. How about

SELECT f.*,IIF(f.datetime>=s.datetime,f.datetime,s.datetime) as last_date FROM first f, second s;
 WHERE f.primarykey = s.primarykey
