これは 'partition by'を正しく使用することですか？

Question

私は レポートをご希望の他の類似の統計情報がいくつかあるため、アナリティクスを使用したいと思います。

Q： Oracle Analyticsを使用すると、空港ごとに1行しか取得できません。 Wernfriedとして

with detail_records as 
(select 1 as passenger_id, 'ATL' as airport, 'E4' as gate, 10 as luggage_weight from dual union all 
select 2 as passenger_id, 'ATL' as airport, 'E4' as gate, 25 as luggage_weight from dual union all 
select 2 as passenger_id, 'SFO' as airport, 'E4' as gate, 20 as luggage_weight from dual union all 
select 3 as passenger_id, 'SFO' as airport, 'E4' as gate, 30 as luggage_weight from dual union all 
select 4 as passenger_id, 'SFO' as airport, 'E4' as gate, 40 as luggage_weight from dual 
) 
select airport, 
     count(*) over (partition by airport) as airport_count, 
     sum(luggage_weight) over (partition by airport, gate) as a_g_weight 
from detail_records 
where gate='E4' 

結果

AIRPORT AIRPORT_COUNT A_G_WEIGHT 
ATL  2    35 
ATL  2    35 
SFO  3    90 
SFO  3    90 
SFO  3    90 

望ましい結果

Airport Airport_count A_G_WEIGHT 
ATL  2    35 
SFO  3    90 

Answer 1

あなたがDISTINCTキーワードを探して、言いました。

「旅客ID」欄には重要であり、重複を避けるために望んでいないので、あなたはそれを呼び出す必要があります。
