Question

我有一个基于所选“结束日期”运行的查询。用户基本上选择结束日期，查询将根据结束日期运行整个YTD的报告。因此，例如，如果我选择“12/3/12”，它应该从1/1/12 - 12/3/12运行报告。如果你在当天运行它，这是有效的......今天我试图在结束日期“12/31/12”运行它但是我没有返回任何结果，因为我认为它试图根据今天的日期得到开始日期？以下是我的询问：

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

将GetDate()替换为@enddate参数，它应该有效：

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

如果您查询：

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

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

它会返回2012-01-01这就是你想要的。
