Hive 对多列配置单元中的不同值进行计数

我有一张像下面这样的桌子

Id col1 col2 col3
1是否否否
2否是否
3是否否否
4否是否

我正在寻找一个配置单元查询，以以下格式显示结果

值col1 col2 col3
是2200
No 2 2 4

select      val                                     as value
           ,count (case when pos = 0 then 1 end)    as col1 
           ,count (case when pos = 1 then 1 end)    as col2
           ,count (case when pos = 2 then 1 end)    as col3 

from        mytable
            lateral view posexplode(array(col1,col2,col3)) pe

group by   val
