如何基於結束日期運行年至今的查詢

Question

我有一個基於「結束日期」選擇運行的查詢。基本上，用戶選擇結束日期，查詢將根據結束日期運行整個YTD的報告。例如，如果我選擇「12/3/12」，它應該從2012年1月1日 - 12/3/12運行報告。如果你在當天運行它，這會起作用...今天我試圖運行結束日期「12/31/12」，但是我沒有返回任何結果，因爲我認爲它是基於今天的日期獲取開始日期？下面是我的查詢：

SELECT  Store_Number, COUNT(DISTINCT Customer_Email_Address) AS Customer_email_address, COUNT(DISTINCT Invoice_Number) AS [Total Cars], 
         @enddate AS End_Date, DATEADD(yy, DATEDIFF(yy, 0, GETDATE()), 0) AS Start_Date 
FROM   Invoice_Tb 
WHERE  (Invoice_Date BETWEEN DATEADD(yy, DATEDIFF(yy, 0, GETDATE()), 0) AND CONVERT(Datetime, @enddate, 102)) 
GROUP BY Store_Number 

Answer 1

與@enddate參數替換GetDate()，它應該工作：

SELECT   
    Store_Number, 
    COUNT(DISTINCT Customer_Email_Address) AS Customer_email_address, 
    COUNT(DISTINCT Invoice_Number) AS [Total Cars], 
    @enddate AS End_Date, 
    DATEADD(yy, DATEDIFF(yy, 0, @enddate), 0) AS Start_Date 
FROM Invoice_Tb 
WHERE (Invoice_Date BETWEEN DATEADD(yy, DATEDIFF(yy, 0, @enddate), 0) 
        AND CONVERT(Datetime, @enddate, 102)) 
GROUP BY Store_Number 

如果查詢：

declare @enddate datetime = '12/31/2012' 

select DATEADD(yy, DATEDIFF(yy, 0, @enddate), 0) 

它將返回2012-01-01這就是你想。
