Re: Getting 'n-1'th record. - Mailing list pgsql-sql

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?
