SQL Server：SELECT上周五下午12点到这个星期五12 PM

Question

我想从上周五12PM到本周五12PM提交所有记录提交给SQL Server用于工资单。我有7天的工作时间，如下图所示，但我需要的是上周五的12PM到本周五的12PM。

SELECT DISTINCT 
    notifications.requestid, 
    Max(timestatuschange), 
    assignedtouser, 
    Count(requestid) AS Total 
FROM 
    notifications 
WHERE 
    timestatuschange >= Dateadd(day, -7, Getdate()) 
    AND notifications.status = 'Yellow' 
    OR timestatuschange >= Dateadd(day, -7, Getdate()) 
    AND notifications.status = 'Red' 
    OR timestatuschange >= Dateadd(day, -7, Getdate()) 
    AND notifications.status = 'Blue' 
GROUP BY 
    requestid, 
    assignedtouser 

Answer 1

由于您使用GETDATE()，我假设今天是星期五，你可以尝试这样的事情

SELECT DATEADD(hour,12,CONVERT(VARCHAR(10),GETDATE(),112)), 
DATEADD(day,-7,DATEADD(hour,12,CONVERT(VARCHAR(10),GETDATE(),112))) 

您所查询的是

DECLARE @StartDate DATETIME = DATEADD(day,-7,DATEADD(hour,12,CONVERT(VARCHAR(10),GETDATE(),112))) 

DECLARE @EndDate DATETIME = DATEADD(hour,12,CONVERT(VARCHAR(10),GETDATE(),112)) 

SELECT DISTINCT notifications.requestid, 
       Max(timestatuschange), 
       assignedtouser, 
       Count(requestid) AS Total 
FROM notifications 
WHERE timestatuschange >= @StartDate 
     AND timestatuschange <= @EndDate 
     AND notifications.status IN ('Yellow','Red','Blue') 
GROUP BY requestid, 
      assignedtouser
