It's just a Bad Idea from the get-go... An ID is supposed to be more abstract than that, really. That said, the IDs in MOST dbs *are* in order, and you *can* just write a query using the result from the one you already have with and get the previous, and another query with to get the next. Limit 1 on both queries. -- Some people have a gift link here. Know what I want? I want you to buy a CD from some indie artist. http://cdbaby.com/browse/from/lynch Yeah, I get a buck.

[PHP] finding next and prev record in mysql
How would I find the next id and the prev id in sql statement like the one below. The id number is not going to be in order so I can't do a or limit 1 on the search SELECT id FROM contacts WHERE category = '5' AND subcategory = '1' AND members_id= '8' ORDER BY lastname
