如何在配置單元中寫入以下mysql查詢？

Question

MySQL查詢：

select * from user_balance_table a where report_date < 20130901 and a.user_id not in (select user_id from user_balance_table a where report_date <20130801); 

我怎麼能寫在蜂巢相同的查詢？

Answer 1

select a.* 
from 
    (select * from user_balance_table 
    where report_date < 20130901 
) a   
    left outer join 
    (select user_id 
    from user_balance_table 
    where report_date <20130801 
    group by user_id 
) b 
on a.user_id=b.user_id and b.user_id is null;
