我在尝试执行子查询时遇到以下错误子查询使用外部查询中未分组的列“s.event\u captured\u dt”

select

to_date(s.event_captured_dt,'DD Mon YYYY')
,count(*) as count_
,(select count(*) 
    from spc_raw_responsys_kanui.sent s1
    where to_date(s1.event_captured_dt,'DD Mon YYYY') between to_date(s.event_captured_dt,'DD Mon YYYY') - 7 and to_date(s.event_captured_dt,'DD Mon YYYY')
) as count7days_

from spc_raw_responsys_kanui.sent s

where 1=1 
and to_date(s.event_captured_dt,'DD Mon YYYY') >= '2020-06-01 00:00:00'

group by to_date(s.event_captured_dt,'DD Mon YYYY')

这就是我想要达到的目标：

如果在子查询中进行预聚合，是否有效？

select
    s.*,
    (
        select count(*) 
        from spc_raw_responsys_kanui.sent s1
        where to_date(s1.event_captured_dt,'DD Mon YYYY') 
            between s.event_captured_date - 7 
            and s.event_captured_date
    ) as count7days_
from (
    select to_date(event_captured_dt,'DD Mon YYYY') event_captured_date, count(*) as count_
    from spc_raw_responsys_kanui.sent s
    where to_date(event_captured_dt,'DD Mon YYYY') >= '2020-06-01 00:00:00'
    group by to_date(event_captured_dt,'DD Mon YYYY')
) s
