輸出求和

Question

我有這樣的查詢：

SELECT 
case [Group] 
    when 1 then 'in' 
    when 0 then 'out' 
    end as traffic 

FROM [GW_Test_Back_Up].[dbo].[ARC_Calls_ReportView] 

與含進/出流量多行，但我真正想要的是隻有兩排，一個用於創建一個新列輸入和輸出之和的總和。我被困在我將如何做到這一點。

Answer 1

我相信你是後：

SELECT 
SUM(CASE WHEN [Group] = 1 then 1 ELSE 0 END) AS InCount, 
SUM(CASE WHEN [Group] = 0 then 1 ELSE 0 END) AS OutCount 
FROM [GW_Test_Back_Up].[dbo].[ARC_Calls_ReportView] 

或者，也許這樣的：

SELECT 'InCount' AS Type, 
SUM(CASE WHEN [Group] = 1 then 1 ELSE 0 END) AS InCount 
FROM [GW_Test_Back_Up].[dbo].[ARC_Calls_ReportView] 
UNION ALL 
SELECT 'OutCount' AS Type, 
SUM(CASE WHEN [Group] = 0 then 1 ELSE 0 END) AS OutCount 
FROM [GW_Test_Back_Up].[dbo].[ARC_Calls_ReportView] 

編輯：

SELECT 
CASE WHEN m.InCount > 10 THEN 'High' ELSE 'Low' END AS InCountStatus 
CASE WHEN m.OutCount > 10 THEN 'High' ELSE 'Low' END AS OutCountStatus 
FROM 
(
    SELECT 
    SUM(CASE WHEN [Group] = 1 then 1 ELSE 0 END) AS InCount, 
    SUM(CASE WHEN [Group] = 0 then 1 ELSE 0 END) AS OutCount 
    FROM [GW_Test_Back_Up].[dbo].[ARC_Calls_ReportView] 
) m
