MySQL select before after row

Question

This is the example table:

Column             | 1st record | 2nd record | 3rd record | 4th record | etc

id (primary)       | 1          | 5                


        

Answer 1

This works:

select a.id, a.name, a.date, a.callValue 
FROM
(
    select @r0 := @r0 + 1 as rownum, id, name, date, callValue from TABLE
    , (SELECT @r0 := 0) r0
) a,
(
    select @r1 := @r1 + 1 rownum, id, name, date, callValue from TABLE
    , (SELECT @r1 := 0) r1 
) b
where b.callValue = val3 and b.rownum between (a.rownum-1 and a.rownum+1)

It expands the table into 2 dimensions so you can compare the rows in the fist table to any set of rows from the second.
