上週的年度數據

Question

我目前正在撰寫一個查詢，該數據會爲我提供上週的數據（讓我們假設爲「SALES」）和上一年同一週的數據。這是我要得到最後幾周的數據，它工作正常：

Set DATEFIRST 1 
Select DATEPArt(dd, DateAdded) AS 'Day of the Month', 
     count(*)AS 'Number of Users' 
from TABLE1 
Where DateAdded >= dateadd(day, -(datepart(dw, getdate()) + 6), CONVERT(date,getdate())) 
    AND DateAdded < dateadd(day, 1-datepart(dw, getdate()), CONVERT(date,getdate())) 
Group by DATEPArt(dd, DateAdded) 
Order by 'Day of the Month' 

現在我想補充另一列，這將使我在同一個星期過去幾年的數據。這是我在想：

Set DATEFIRST 1 
Select DATEPArt(dd, DateAdded) AS 'Day of the Month', 
     count(*)AS 'Number of Users' 
from TABLE1 
Where DateAdded >= DATEADD(yy,DATEDIFF(yy,0,GETDATE())-1,0) 
    AND DateAdded < DATEADD(yy,DATEDIFF(yy,0,GETDATE())+1,0) 
    AND DateAdded >= dateadd(day, -(datepart(dw, getdate()) + 6), CONVERT(date,getdate())) 
    AND DateAdded < dateadd(day, 1-datepart(dw, getdate()), CONVERT(date,getdate())) 
Group by DATEPArt(dd, DateAdded), DateAdded 
Order by 'Day of the Month' 

問題是，我仍然得到最後一週的數字（今年，我需要它是去年）。這導致我相信錯誤必須在某處：

DateAdded >= DATEADD(yy,DATEDIFF(yy,0,GETDATE())-1,0) 
AND DateAdded < DATEADD(yy,DATEDIFF(yy,0,GETDATE())+1,0) 

我很感謝大家的幫助！

你正在尋找一個OR條件

WHERE (DateAdded >= DATEADD(yy,DATEDIFF(yy,0,GETDATE())-1,0) 
    AND DateAdded < DATEADD(yy,DATEDIFF(yy,0,GETDATE())+1,0)) 

OR (DateAdded >= dateadd(day, -(datepart(dw, getdate()) + 6), CONVERT(date,getdate())) 
    AND DateAdded < dateadd(day, 1-datepart(dw, getdate()), CONVERT(date,getdate())))
