Answer 1

不确定您要执行的操作，但cte后面应该是另一个cte或select，insert。

您可以使用

select name, title,
  max(case when special = 'super' then max_power end) as Super_max,
  max(case when special = 'awesome' then max_power end) as Awesome_max,
  min(case when special = 'super' then max_power end) as Super_min,
  min(case when special = 'awesome' then max_power end) as Awesome_min
from mytable
group by name, title

如果列名必须相同，请使用union all。

select name, title,
  max(case when special = 'super' then max_power end) as Super,
  max(case when special = 'awesome' then max_power end) as Awesome
from mytable
group by name, title
union all
select name, title,
  min(case when special = 'super' then max_power end) as Super,
  min(case when special = 'awesome' then max_power end) as Awesome
from mytable
group by name, title
