Question

In PHP, I’ve a contest question such as “How many people will participate ?”. I need to select the 10 closest answers near this total participants.

I’ve a table called answers with an ID and number field.
Let’s say the total participants are 100 and I want 10 results.

I need to select the 10 results where number is closest to 100. It should be above and below 100.

How could I do that ?

Thanks,

Answer 1

Select the (abs(delta))…

select id, number, abs(100 - number) as delta
from mytable
order by delta
limit 0, 10

Something like this.
