i want to write a MySQL query to rank scores. If there is a tie between two scores, both should have the same ranking. also after a tie, the next ranking number should be the next consecutive integer value. In other words, there should be no "holes" between ranks.
+----+-------+
| Id | Score |
+----+-------+
| 1 | 3.50 |
| 2 | 3.65 |
| 3 | 4.00 |
| 4 | 3.85 |
| 5 | 4.00 |
| 6 | 3.65 |
+----+-------+
given the above Scores table, the query should generate the following report (order by highest score)
+-------+------+
| Score | Rank |
+-------+------+
| 4.00 | 1 |
| 4.00 | 1 |
| 3.85 | 2 |
| 3.65 | 3 |
| 3.65 | 3 |
| 3.50 | 4 |
+-------+------+
i tried something like the below set @pk1 =''; set @rn1 =1; set @val =1;
SELECT score,Rank
FROM
(
SELECT score,
@rn1 := if(@pk1=score,@rn1, @rn1+@val) as Rank,
@val := if(@pk1=score,@val+1, 1 ) as value,
@pk1 := score
FROM
(SELECT score FROM scores ORDER BY score) as rank) as scores;
but the above didnt work can anyone help on this
