MySql Logical Order By

Tôi khuyên bạn nên sử dụng cách sắp xếp như trong How Not To Sort By Average Rating

Demo:

CREATE TABLE clans(id INT, name VARCHAR(100), warswon INT, warslost INT);

INSERT INTO clans VALUES (1, 'aaa',  208, 6), (2, 'bbb', 103, 0);

SELECT id, name,warswon, warslost,((warswon + 1.9208) / (warswon + warslost) - 
                 1.96 * SQRT((warswon * warslost) / (warswon + warslost) + 0.9604) / 
                          (warswon + warslost)) / (1 + 3.8416 / (warswon + warslost)) 
       AS ci_lower_bound 
FROM clans 
ORDER BY ci_lower_bound DESC;
