postgresql - Matching algorithm in SQL

Question

I have the following table in my database.

# select * FROM matches;
 name | prop |  rank
------+------+-------
 carl |    1 |     4
 carl |    2 |     3
 carl |    3 |     9
 alex |    1 |     8
 alex |    2 |     5
 alex |    3 |     6
 alex |    3 |     8
 alex |    2 |    11
 anna |    3 |     8
 anna |    3 |    13
 anna |    2 |    14
(11 rows)

Each person is ranked at work by different properties/criterias called 'prop' and the performance is called 'rank'. The table contains multiple values of (name, prop) as the example shows. I want to get the best candidate following from some requirements. E.g. I need a candidate that have (prop=1 AND rank > 5) and (prop=3 AND rank >= 8). Then we must be able to sort the candidates by their rankings to get the best candidate.

EDIT: Each person must fulfill ALL requirements

How can I do this in SQL?

Answer 1

select x.name, max(x.rank) 
from matches x
join (
    select name from matches where prop = 1 AND rank > 5
    intersect
    select name from matches where prop = 3 AND rank >= 8
) y
    on x.name = y.name 
group by x.name
order by max(rank);
