Question

I have a table in database that is having unique id’s.
I have a page where one particular id is shown and link is given for next and previous id’s.
I have to get those prev and next id’s by one single mysql query .All i have is that particular id on whose data we are currently working on.
id’s are not consecutive numbers as sometimes some id’s get deleted also.(for eg. 1,2,3,7,9,10,15 etc)

So how can i get these two previous and next id’s in one single query????

Answer 1

SELECT
   (SELECT id FROM YourTable WHERE id < YourId ORDER BY id DESC LIMIT 1) AS prev,
   (SELECT id FROM YourTable WHERE id > YourId ORDER BY id ASC LIMIT 1) AS next
;

Replace YourId with the actual id and replace YourTable with valid table name. If any of the values will be NULL then there is no next/prev element to the given.
