MySQL search, previous record

Hi
I am creating a shop and my client has just asked if they can have a next and previous button when viewing a product. These two links would also feature the names of the next and previous products.
When the products are listed they are listed on the page in the order of the primary key descending.
So when they are viewing a product with a particular id what is the easiet way to find the next a previous product in the databse and display their details (name).
Many thanks
Matt

Well, asuming you have the current id on your page a query sorting the keys would do the trick.
// find the next entry.
// sql server
select top 1 * from products where key > @curKey order by key asc
// mysql
select * from products where key > @curKey order by key asc LIMIT 1
 
// find the previous entry.
// sql server
select top 1 * from products where key < @curKey order by key desc
//mysql
select * from products where key < @curKey order by key desc LIMIT 1
