Let's say I have a table in a database like [this table](http://sqlfiddle.com/#!2/e1aaf/11). Let's say that I want to get the entries on the left and right of the entry whose the primary key is equal to 5 (or any other primary key). So in our case, I want to get the entries whose primary key is equal to 4 and 6 respectively. What is the SQL query that will give me such result? Can you guys translate the SQL query into a [find('all')](http://book.cakephp.org/1.3/en/The-Manual/Developing-with-CakePHP/Models.html#find-all) CakePHP query?

Thank you

**NOTE: The ids are not necessarily contiguous, meaning, they do not necessarily follow the 1, 2, 3, 4, 5, 6, 7, 8 sequence. I can have something like 1, 5, 13, 44, 66, 123, etc**
