ROW_NUMBER, RANK, or DENSE_RANK to have the SAME order number if there are rows with same values - sqlite

Question

PROBLEM
Form a scoreboard with position number, player name and best score. If two players have the same score, they share the position and the names are in alpabetical order. (See example.)
I have two tables
INSERT INTO players (id,name) VALUES (1, Uolevi),(2,Maija),(3,Liisa),(4,Kaaleppi),(5,Kotivalo);
INSERT INTO results (id, player_id, score) VALUES (1, 1, 100), (2, 2, 200), (3, 3, 200), (4, 4, 100), (5, 5, 50);
The expected result is:
Order
Name
Score
1
Liisa
200
1
Maija
200
3
Kaaleppi
100
3
Uolevi
100
5
Kotivalo
50
Please look carefully at the order number. Because there are 2 rows with order number 1, the next order number will be 3, instead of 2.

Answer 1

Here is a possible solution:
WITH
places AS (
SELECT row_number() OVER (ORDER BY score DESC, name) AS place, name, score
FROM players
JOIN results ON players.id = results.player_id
)
SELECT first_value(place) OVER (PARTITION BY score ORDER BY place) AS place, name, score
FROM places ORDER BY score DESC, name;
See the fiddle.

Answer 2

You need rank() to keep ranking if there is a tie. dense_rank() when you don't need gaps between ranks.
select rank() over (order by r.score desc) as order1,
dense_rank() over (order by r.score desc) as order2,
p.name,
r.score
from players p
join results r
on p.id = r.player_id
order by r.score desc, p.name;
Outcome (include both rank() and dense_rank() for your reference).
| order1 | order2 | name | score |
+--------+--------+-----------+-------+
| 1 | 1 | Liisa | 200 |
| 1 | 1 | Maija | 200 |
| 3 | 2 | Kaaleppi | 100 |
| 3 | 2 | Uolevi | 100 |
| 5 | 3 | Kotivalo | 50 |
