Write a SQL query to rank scores. If there is a tie between two scores, both should have the same ranking. Note that 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 | +----+-------+
For example, given the above Scores table, your 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 | +-------+------+
Solution:
SELECT T2.Score AS Score, ( SELECT COUNT(*) + 1 FROM (SELECT T1.Score FROM Scores T1 GROUP BY Score ORDER BY Score DESC) TEMP WHERE T2.Score < TEMP.Score ) AS Rank FROM Scores T2 ORDER BY Score DESC
