How to SUM() from an offset through the end of the table?
If `SELECT SUM(amount) FROM transactions ORDER BY order LIMIT 0, 50 ` sums the `amount` field for the first 50 records in a table, how do a sum all records *after* the first 50?  In other words, I'd like to do something like `SELECT SUM(amount) from transactions ORDER BY order LIMIT 50, *`, but that doesn't work.
