在另一個查詢 (Athena) 中使用一個 SQL 查詢的結果

Question

我有點堅持如何做到這一點，所以希望有人能指出我正確的方向。

我有這個簡單的查詢：

SELECT acchl.is_current,
       acchl.aircraft_registration_number,
       acchl.aircraft_transponder_code
FROM   fleets.aircraft_all_history_latest acchl
WHERE  acchl.is_current = true

然后我想使用該查詢的結果來查找所有重復的飛機應答器代碼以及飛機注冊號，使用類似自連接的方法來獲取可能具有重復值的實際行，如下所示：

select s.id, s.col_maybe_dups 
  from sometab s 
  join (select col_maybe_dups as cd 
          from sometab 
         group by cd 
        having count(*) > 1) x 
    on x.cd = s.col_maybe_dups;

看起來不錯！

你也可以用它WITH

WITH data as (
SELECT acchl.is_current,
       acchl.aircraft_registration_number,
       acchl.aircraft_transponder_code
FROM   fleets.aircraft_all_history_latest acchl
WHERE  acchl.is_current
)

select * from data
where aircraft_transponder_code in 
  (select aircraft_transponder_code 
   from data 
   group by 1
   having count(*) > 1
  )
