MySQL: select 5 rows before and after specific row

Question

I have table called \"users\" and need to select 2 rows before and after specific row, sorted by users.score ASC

users table (structure):

id     name         


        

Answer 1

Using union all and subqueries to limit the records should do it:

select * from  users where id = 5
union all (
  select * from users 
  where score <  (select score from users where id = 5) 
  order by score desc limit 2
) 
union all (
  select * from users 
  where score > (select score from users where id = 5) 
  order by score asc limit 2
) 
order by score

Sample SQL Fiddle

Edit: I think a better method is to number the rows according to score and then select the rows with number -2 and +2 from the rows of id 5:

select id, name, score 
from (select 
      t.*, @rownum1 := @rownum1 + 1 as rank
      from users t, (select @rownum1 := 0) r
      order by score
     ) a,
     (select rank from (
        select t.*, 
        @rownum := @rownum + 1 as rank
        from users t, (select @rownum := 0) r
        order by score
     ) t
      where id = 5
   ) b
where b.rank between a.rank -2 and a.rank+2
order by score;
