我有3张付款方式表（信用卡-SADAD- at_place）。
我从所有这些数据中检索数据，并使用Sum来汇总所有
的价格select Payment_Date, count(Payment_Date) as Transaction_COUNT, sum(OWNER_Amount) as OWNER_Amount , sum (commission) as commission,sum(Total_Amount) As Sub_total
from (
select format(PAYMENT_POOL_CREDIT.PAYMENT_POOL_CREDIT_DATE,'dd/MM/yyyy') as Payment_Date,PAYMENT_POOL_CREDIT.PAYMENT_POOL_CREDIT_OWNER_MONEY as OWNER_Amount,PAYMENT_POOL_CREDIT.PAYMENT_POOL_CREDIT_TAX_MONEY as commission, PAYMENT_POOL_CREDIT.PAYMENT_POOL_CREDIT_OWNER_MONEY+PAYMENT_POOL_CREDIT.PAYMENT_POOL_CREDIT_TAX_MONEY as Total_Amount from PAYMENT_POOL_CREDIT
union all
select format(PAYMENT_POOL_SADAD.PAYMENT_POOL_SADAD_DATE,'dd/MM/yyyy') as Payment_Date,PAYMENT_POOL_SADAD.PAYMENT_POOL_SADAD_OWNER_MONEY as OWNER_Amount,PAYMENT_POOL_SADAD.PAYMENT_POOL_SADAD_TAX_MONEY as commission ,PAYMENT_POOL_SADAD.PAYMENT_POOL_SADAD_OWNER_MONEY+PAYMENT_POOL_SADAD.PAYMENT_POOL_SADAD_TAX_MONEY as Total_Amount from PAYMENT_POOL_SADAD
union all
select format(PAYMENT_POOL_AT_PLACE.PAYMENT_POOL_AT_PLACE_DATE,'dd/MM/yyyy') as Payment_Date,PAYMENT_POOL_AT_PLACE.PAYMENT_POOL_AT_PLACE_OWNER_MONEY as OWNER_Amount,PAYMENT_POOL_AT_PLACE.PAYMENT_POOL_AT_PLACE_TAX_MONEY as commission,PAYMENT_POOL_AT_PLACE.PAYMENT_POOL_AT_PLACE_OWNER_MONEY+PAYMENT_POOL_AT_PLACE.PAYMENT_POOL_AT_PLACE_TAX_MONEY as Total_Amount from PAYMENT_POOL_AT_PLACE
) as t
group by Payment_Date
现在我想要的是将另一个聚合列加入到上一个查询中 从这个聚合。
select format(PAYMENT_POOL_AT_PLACE.PAYMENT_POOL_AT_PLACE_DATE,'dd/MM/yyyy') as Payment_Date, sum(PAYMENT_POOL_AT_PLACE.PAYMENT_POOL_AT_PLACE_OWNER_MONEY+PAYMENT_POOL_AT_PLACE.PAYMENT_POOL_AT_PLACE_TAX_MONEY) as Total_Amount_At_Place from PAYMENT_POOL_AT_PLACE
group by format(PAYMENT_POOL_AT_PLACE.PAYMENT_POOL_AT_PLACE_DATE,'dd/MM/yyyy')
有人可以帮忙吗？
这是样本表
PAYMENT_POOL_CREDIT

11/02/2017 | 500.00 | 40.00 | 540.00
15/05/2016 | 242.00 | 10.00 | 252.00
11/02/2017 | 100.00 | 30.00 | 130.00
15/05/2016 | 620.00 | 60.00 | 680.00
PAYMENT_POOL_SADAD
Payment_Date | OWNER_Amount | commission | Total_Amount
05/05/2016 | 5000.00 | 200.00 | 5200.00

15/05/2016 | 500.00 | 200.00 | 700.00
我正在寻找的结果看起来像这样
Payment_Date | Transaction_COUNT | OWNER_Amount | Total_commission | Total_Amount | Total_at_palce
05/05/2016 | 1 | 5000.00 | 200.00 | 5200.00 | NULL
11/02/2017 | 4 | 1052.00 | 140.00 | 1192.00 | NULL
15/05/2016 | 6 | 2512.00 | 590.00 | 3102.00 | 1400
22/06/2016 | 1 | 500.00 | 300.00 | 800.00 | 800

您可以在union all派生表中添加一列来区分源，而不是加入这些查询，因此您可以使用条件聚合同时从total_amount获取payment_pool_at_place ，像这样：
select Payment_Date
, count(Payment_Date) as Transaction_count
, sum(owner_Amount) as owner_Amount
, sum(commission) as commission
, sum(Total_Amount) as Sub_total
, sum(case when src = 'ppap' then Total_Amount_At_Place end) as Total_Amount_At_Place
from (
select format(ppc.payment_pool_credit_date, 'dd/mm/yyyy') as Payment_Date
, ppc.payment_pool_credit_owner_money as owner_Amount
, ppc.payment_pool_credit_tax_money as commission
, ppc.payment_pool_credit_owner_money
+ ppc.payment_pool_credit_tax_money as Total_Amount
, src = convert(varchar(4),'ppc')
from payment_pool_credit as ppc
union all
select format(pps.payment_pool_sadad_date, 'dd/mm/yyyy') as Payment_Date
, pps.payment_pool_sadad_owner_money as owner_Amount
, pps.payment_pool_sadad_tax_money as commission
, pps.payment_pool_sadad_owner_money
+ pps.payment_pool_sadad_tax_money as Total_Amount
, src = convert(varchar(4),'pps')
from payment_pool_sadad as pps
union all
select format(ppap.payment_pool_at_place_date, 'dd/mm/yyyy') as Payment_Date
, ppap.payment_pool_at_place_owner_money as owner_Amount
, ppap.payment_pool_at_place_tax_money as commission
, ppap.payment_pool_at_place_owner_money
+ ppap.payment_pool_at_place_tax_money as Total_Amount
, src = convert(varchar(4),'ppap')
from payment_pool_at_place as ppap
) as t
group by Payment_Date
更新了新样本：
select PaymentDate
, count(Payment_Date) as Transaction_count
, sum(owner_Amount) as owner_amount
, sum(commission) as commission
, sum(Total_Amount) as Sub_total
, sum(case when src = 'ppap' then Total_Amount end) as Total_Amount_At_Place
from (
select Payment_Date
, ppc.owner_amount as owner_Amount
, ppc.tax_amount as commission
, ppc.owner_amount
+ ppc.tax_amount as Total_Amount
, src = convert(varchar(4),'ppc')
from payment_pool_credit as ppc
union all
select Payment_Date
, pps.owner_amount as owner_Amount
, pps.tax_amount as commission
, pps.owner_amount
+ pps.tax_amount as Total_Amount
, src = convert(varchar(4),'pps')
from payment_pool_sadad as pps
union all
select Payment_Date
, ppap.owner_amount as owner_Amount
, ppap.tax_amount as commission
, ppap.owner_amount
+ ppap.tax_amount as Total_Amount
, src = convert(varchar(4),'ppap')
from payment_pool_at_place as ppap
) as t
where Payment_Date != '20160617' /* this is missing from your desired results */
group by Payment_Date
order by format(payment_date,'dd/MM/yyyy') /* to match desired results order */
返回：
