Re: Getting 'n-1'th record.

You're making this much harder than it needs to be.

If you want the "nth" record, then you have to be supplying the database
with an ORDER BY. For the next-to-last record, simply reverse the ORDER
BY and take the second record.

e.g.:

If you want the next-to-last (n-1) record from:
SELECT * FROM syslog
ORDER BY entrytime;

Then ask for:
SELECT * FROM syslog
ORDER BY entrytime DESC
LIMIT 1 OFFSET 1;

Easy, no?
