MySQL dense_rank 不跳过数字

Question

I fairly new to MYSQL and I'm having trouble getting dense rank to work correctly, I was hoping someone would be able to help adjust my query to get the desired results. Issue I'm having is after a ranking that is the same it goes to the next number instead of skipping a number. I have shown both current results and desired results below.

        SELECT  gameid,
            score
         , IF(score <> @pscore,@i:=@i+1,@i:=@i) rank
         , @pscore := score          
        FROM playerstats x
        , (SELECT @i:=0,@prev:='',@pscore:='') vars 
        ORDER 
        BY score DESC;

Current Results:

Basically you need to sort the tdata before you rank it. MySQL

 CREATE TABLE playerstats ( `Score` INTEGER, `Player` VARCHAR(11) ); INSERT INTO playerstats (`Score`, `Player`) VALUES ('2543', 'jkoffa'), ('2204', 'probins'), ('2010', 'rwatson'), ('2010', 'nbk'), ('2010', 'tthamos'), ('1950', 'en,acdonald'), ('1927', 'dmaginis');

 SELECT `Player`,IF(@score <> `Score`, @rn:= @rn + @cor +1, @rn:= @rn) rnknumber,IF(@score = `Score`, IF(@cor > 0,@cor:= @cor +1,@cor:= 1), @cor:= 0) correction,@score:= `Score` 'Score' FROM (SELECT `Score`, `Player` FROM playerstats ORDER BY Score DESC) t1, (SELECT @score:= -1) t2,(SELECT @rn:= 0) t3,(SELECT @cor:= 0) t4

 Player | rnknumber | correction | Score:---------- |:-------- | ---------: |  ----: jkoffa |  1 |  0 |  2543 probins |  2 |  0 |  2204 rwatson |3 |  0 |  2010 nbk |  3 |  1 |  2010 tthamos |  3 |  2 |  2010 en,acdonald |  6 |  0 |  1950 dmaginis | 7 |  0 |  1927

Answer 2

nbk - I apologize for the pictures will make sure to use text next time. Thank you again for your time. Unfortunately it only works if data is entered in the correct order. If you were to take the bottom three entries and put them in first then tthomos would be ranked #1.

CREATE TABLE playerstats  (
  `Score` INTEGER,
  `Player` VARCHAR(11)
);

INSERT INTO playerstats 
  (`Score`, `Player`)
VALUES
  ('2010', 'tthamos'),
  ('1950', 'acdonald'),
  ('1927', 'dmaginis'),
  ('2543', 'jkoffa'),
  ('2204', 'probins'),
  ('2010', 'rwatson');

then ran:

SELECT
`Player`
,IF(@score <> `Score` , @rn := @rn + @cor +1, @rn:= @rn) rnknumber
,IF(@score = `Score` , @cor := 1, @cor := 0) correction
,@score := `Score` 'Score'
FROM
(SELECT `Score`, `Player` FROM playerstats ORDER BY Score DESC) t1
, (SELECT @score := -1) t2
,(SELECT @rn := 0) t3,(SELECT @cor := 0) t4

You would get:

tthamos   1     0   2010
acdonal   2     0   1950
dmaginis  3     0   1927
jkoffa    4     0   2543
probins   5     0   2204
rwatshon  6     0   2010
