派生列的 Hive 查询并找到派生列的总数

问题描述

我有一个场景，credit_Date、debit_date 和loan_date 可以相同。输出表有以下列

日期：应该结合credit_date、debit_date和loan_date（credit_date、debit_date和loan_date可以相同（或）为空）

Credit_payment：查找给定信用日期、实体、货币、所有者的信用金额总和

Debit_payment：查找给定借记日期、实体、货币、所有者的借记金额总和

Loan_payment：查找给定贷款日期、实体、货币、所有者的贷款金额总和，

实体：来自表 1 的值

货币：表 1 中的值

所有者：表 1 中的值

总计：（credit_payment + debit_payement+loan_payment）的总和

我试过下面的查询但没有用

insert into table2 
select *
from (
    select credit_date as date,sum(credit_amount) as credit_payment,null as debit_payment,null as loan_payment,entity,owner,currency
    from table1
    group by credit_date,currency
    union all
    select debit_date as date,null as credit_payment,sum(debit_amount) as debit_payment,currency
    from table1
    group by debit_date,currency 
    union all
    select loan_date as date,sum(loan_amount) as loan_payment,currency
    from table1
    group by loan_date,currency
) t
order by date;
