Check which member has the most connections

Question

I want to create a query, based on excel file.

I have a two columns table that shows transactions between friends. I want to know which member has the most friends (it doesn't matter if he being paid or pays money).

Of course, two transations to or from the same person counts as one (I want to see how many friends, not how many times did he pay/got paid) table

paid	pays
18	14
1	17
20	12
11	12
8	20
3	6
4	2
20	9
10	8
20	5
16	14
2	5
1	12
10	14
3	6
4	14
2	6
11	14

Answer 1

select max value from sub query like below example

select paid from (select paid,sum(pays) as `pays` from tbl) where pays=max(pays)
