MySQL查詢問題理貨

Question

我有一個表在MySQL olympic和字段名

country varchar, gold(int), silver(int), bronze(int) 

請幫我查詢到安排升序排列，就像奧運金牌列表中的數據。

Answer 1

SELECT * 
FROM `olympic` 
ORDER BY `gold` DESC, `silver` DESC, `bronze` DESC; 

Answer 2

SELECT country, gold, silver, bronze 
FROM olympic 
ORDER BY gold DESC, silver DESC, bronze DESC; 

Answer 3

試試這個：

select 
country, 
Sum(gold) as gold, 
Sum(silver) as silver, 
Sum(bronze) as bronze 
from olympic 
group by country 
order by 
gold desc, silver desc, bronze desc 

這會給你的國家的名單與他們取得獎牌。
