按国家/地区计算选择COUNT（国家/地区）组

Question

我试图在我的网站上获取国家访问次数。我有一个带有uid，国家和日期的SQL表。我然后尝试从SQL中提取计数，我需要在有序数组中计数，如

• US - 53
• 英国 - 47
• CA - 45
• 等

自从我使用SQL查询以来，已经很长时间了，我相信它的GROUP BY失败了。

SELECT COUNT(cfCountry) AS count FROM countryTracking GROUP BY cfCountry

但这只会回归：

• 8
• 4
• 47
• 2
• 4
• 2
• 等

如何让它返回订购的国家/地区以及前面的国家？

Answer 1

你可以尝试添加像这样的计数

SELECT 
    country,
    COUNT(country) as count
FROM countryTracking
GROUP BY country
ORDER BY COUNT(country)

Answer 2

SELECT COUNT(cfCountry) AS COUNT,
       cfCountry
FROM countryTracking
GROUP BY cfCountry
ORDER BY COUNT DESC;

Answer 3

只需在计数旁边添加要显示的字段，就应在结果集中显示此字段。

SELECT cfCountry, COUNT(cfCountry) AS count
FROM countryTracking c
GROUP BY cfCountry
