来自同一 table 的两个 sql 查询的总和结果

Question

我提出了这两个查询，以根据特定的 where 子句在单个 table 上查找字段的总和：

Select Sum(dbo.Charges.[TRANS AMT]) as Total1  
from dbo.Charges 
where (dbo.Charges.[TRAN ID] IN (100, 20, 50, 52, 55, 60, 600))   

Select Sum(dbo.Charges.[TRANS AMT]) as Total2  
from dbo.Charges 
where dbo.Charges.[TRAN ID] = 200

我无法找到一种方法来将两个查询的结果相加以获得总计。关于如何执行此操作有什么建议吗？

Answer 1

只需在 IN 子句中添加 [TRAN ID] 200 :

SELECT SUM(dbo.Charges.[TRANS AMT]) AS GRAND_TOTAL
FROM dbo.Charges 
WHERE dbo.Charges.[TRAN ID] IN (100, 20, 50, 52, 55, 60, 600, 200);

获取所有金额：

SELECT
   SUM(CASE WHEN dbo.Charges.[TRANS AMT] <> 200 THEN dbo.Charges.[TRANS AMT] END) AS Total1,
   SUM(CASE WHEN dbo.Charges.[TRANS AMT] = 200 THEN dbo.Charges.[TRANS AMT] END) AS Total2,
   SUM(dbo.Charges.[TRANS AMT]) AS GRAND_TOTAL
FROM dbo.Charges 
WHERE dbo.Charges.[TRAN ID] IN (100, 20, 50, 52, 55, 60, 600, 200);

Answer 2

由于产生这些总和的行是互斥的，您可以将 [TRAN ID] 组合在它们的 where 子句中：

SELECT SUM(dbo.Charges.[TRANS AMT]) as GrandTotal
FROM   dbo.Charges
WHERE  dbo.Charges.[TRAN ID] IN (100, 20, 50, 52, 55, 60, 600, 200)
