</html>现在，我需要找到哪种颜色最常见？ 我使用以下查询获得了所有颜色的计数。
name red black white
US 1 1 1
UK 0 1 0
EU 1 1 0
AUS 0 0 0
这将给出以下输出：
select colorName,count(name) as total
from
(select
case
when red == 1 then 'red'
when black == 1 then 'black'
end as colorName, name from countrytable)a
group by colorName;
但我希望获得最常见的价值，即＆＃34; black＆＃34;。我怎么能在Hive中这样做？
red black white
2 3 1
答案 0 :(得分：0)
添加另一个步骤，按计数的降序排序/排序，并将其限制在前1条记录。
select colorName,count(name) as total
from
(select
case
when red == 1 then 'red'
when black == 1 then 'black'
end as colorName, name from countrytable)a
group by colorName
ORDER BY count(name) DESC
LIMIT 1;
