A friend of me asked me long time ago: “How can I have a ranking on a result with MySQL?”. Now I found some time to write it down:
Lets do first some preparation for the example:
CREATE TABLE sales (
id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY
, fruit VARCHAR(32)
, amount DECIMAL
);
INSERT INTO sales
VALUES (NULL, 'apple', 12.75), (NULL, 'orange', 1.89), (NULL, 'pear', 19.23)
, (NULL, 'banana', 4.25), (NULL, 'cherry', 123.75), (NULL, 'plum', 23.15)
;
Now lets query:
SELECT …
