好吧......我不确定我是否理解你真正想要的东西，但根据你所描述的内容，我将采取刺痛措施......

(select 'survey1' as survey, survey1 as forms, count(*) as options from some_table
group by survey, survey1 order by options desc)

union all

(select 'survey2' as survey, survey2 as forms, count(*) as options from some_table
group by survey, survey2 order by options desc)

union all

(select 'survey3' as survey, survey3 as forms, count(*) as options from some_table
group by survey, survey3 order by options desc)

union all

(select 'survey4' as survey, survey4 as forms, count(*) as options from some_table
group by survey, survey4 order by options desc)

union all

(select 'survey5' as survey, survey5 as forms, count(*) as options from some_table
group by survey, survey5 order by options desc)

union all

(select 'survey6' as survey, survey6 as forms, count(*) as options from some_table
group by survey, survey6 order by options desc)

这将返回包含该选项的一组结果，以及它在特定调查的列中出现的次数。我添加了一个专栏，以便能够判断哪些结果来自哪个调查。
