Answer 1

您可以使用SQL执行此操作：

select 
count(*),
 YEAR(from_unixtime(ts/1000)),
        MONTH(from_unixtime(ts/1000)),
        DAY(from_unixtime(ts/1000)),
        hour(from_unixtime(ts/1000)),
        minute(from_unixtime(ts/1000)),
        second(from_unixtime(ts/1000))
from pointValues 
where
  YEAR(from_unixtime(ts/1000))  = YEAR(NOW()) and
  MONTH(from_unixtime(ts/1000))  = Month(NOW()) and
  DAY(from_unixtime(ts/1000))  = DAY(NOW())
group by
    YEAR(from_unixtime(ts/1000)),
        MONTH(from_unixtime(ts/1000)),
        DAY(from_unixtime(ts/1000)),
        hour(from_unixtime(ts/1000)),
        minute(from_unixtime(ts/1000)),
        second(from_unixtime(ts/1000))
Having count(*) >5
order by count(*) DESC
