This isn't implemented in Standard demo, as there is no notion
of "previous" and "next" product.
It's simple to do it, though. If your SKUs are consecutive numbers
(or obtainable by formula given current SKU) you don't even need a search,
just provide a link to a flypage with SKU -1, +1 or similar.
If not, then a simple SQL query (or two actually) that return the
previous and next SKU will do.
That implies your SQL column is of proper type so that you can
use < and > operators.
Something like this would work (untested):
sql="(select sku from products where id < $THIS order by id desc limit 1)
union all (select sku from products where id > $THIS order by id limit 1)"
Previous product, [sql-code]
Next product, [sql-code]
