• SELECT query with CASE condition and SUM() 5个答案

Select SUM(IF(CPaymentType='Check', CAmount, 0)) as PaymentAmountCheck, 
       SUM(IF(CPaymentType='Cash', CAmount, 0)) as PaymentAmountCash 
from TableOrderPayment 
where CPaymentType IN ('Check','Cash') and CDate<=SYSDATETIME() and CStatus='Active';

我想总结PaymentAmountCheck和PaymentAmountCash，任何人都可以帮助我

Answer 1

您可以使用派生选项添加这两个字段，如下所示：

SELECT PaymentAmountCheck, 
      PaymentAmountCash, 
      PaymentAmountCheck + PaymentAmountCash AS TotalAmount
FROM (
 Select SUM(IIF(CPaymentType='Check', CAmount, 0)) as PaymentAmountCheck, 
       SUM(IIF(CPaymentType='Cash', CAmount, 0)) as PaymentAmountCash,
 from TableOrderPayment 
 where CPaymentType IN ('Check','Cash') and CDate<=SYSDATETIME() and CStatus='Active';
) AS Q;

同样在SQL Server中，您可以使用IIF

Answer 2

因为在你提到的CPaymentType的where子句中，你可以在sum(CAmount)中添加select，它将为你提供PaymentAmountCheck和PaymentAmountCash的总和。

  Select SUM(IF(CPaymentType='Check', CAmount, 0)) as PaymentAmountCheck, 
           SUM(IF(CPaymentType='Cash', CAmount, 0)) as PaymentAmountCash ,
           sum(CAmount) total
    from TableOrderPayment 
    where CPaymentType IN ('Check','Cash') and CDate<=SYSDATETIME() and CStatus='Active';
