として、以下のデータが含まれていない参加左各顧客。私は左に参加しましたが、すべての組み合わせでgettin 420行をしました。間違っています。顧客ごとに20行を取得することをお勧めします。

Answer 1

cust_noとホストのすべての組み合わせを見つけるには、それと。

select t.cust_no, 
    t.host, 
    coalesce(u.usage, 0) usage, 
    coalesce(u.usageduration, 0) usageduration 
from (
    select * 
    from (
     select distinct cust_no 
     from user 
     ) u 
    cross join top20 t 
    ) t 
left join user u on t.cust_no = u.cust_no 
    and t.host = u.host;
