Oh, Mighty LJ Brain: SQL for "next" and "previous" entries?

[elfs]

Oh, mightly LJ brain, riddle me this:

I have a table in a MySQL (well, okay, it's Sqlite3 right now, but it'll my MySQL in production) database, and the primary keys are known to not be contiguous. That's important.

It's possible to construct a WHERE clause giving you a single item, if that items qualties are unique enough. Is it possible, using some magic combination of WHERE and ORDER BY and something I don't know, to say "give me unique item N, and using the rule of the ORDER BY clause, also give me the next and previous objects?"

I don't think you can do this in a single select (that is, without using subselects) .

If you are willing to load the next and previous objects in dedicated queries, you can use something like:

select *
from table
where id > ?
order by id
limit 1
