Question

所以我需要编写一个存储过程来生成报告。在本报告中，我需要显示支票金额和支票计数的平均每日计数。这就是我现在所拥有的：

SELECT  SendingBank,
        CheckCount As TotalCount,
        CheckAmt As TotalAmt,
        AVG(CheckCount/30) AS AvgDailyCount,
        AVG(CheckAmt/30) AS AvgDailyAmt
FROM tblRptT001 
WHERE InwardClearingDate = @asInwardClearingDt
GROUP BY InwardClearingDate, SendingBank, CheckCount, CheckAmt
ORDER BY InwardClearingDate

我知道我为平均数做了什么是完全错误的，我坚持认为，因为不是每个月都有相同的天数。我测试了这个sp并且它工作，除了我想要的平均场的方式。

关于如何处理这个问题的任何想法？非常感谢任何形式的帮助。谢谢！

修改：这是示例数据

InwardClearingDate  SendingBank     CheckCount  CheckAmt
2014-03-03          ABC Bank        1800        70000.00
2014-03-21          BBC Bank        526         456090.00

和我想要的结果

Sending Bank|Total Count| Total Amt| Daily Avg Count| Daily Avg Amt
ABC Bank    | 1800      | 70000.00 | 60             |2333.00

参数是内向结算日期，例如2014-03-03。

Answer 1

可能是这样的

SELECT S.SendingBank,
       S.TotalCount,
       S.TotalAmt,
       AVG(T.CheckCount) AS AvgDailyCount, 
       AVG(T.CheckAmt) AS AvgDailyAmt
FROM
(
  SELECT SendingBank, CheckCount As TotalCount, CheckAmt As TotalAmt
  FROM tblRptT001 
  WHERE InwardClearingDate = @asInwardClearingDt 
  GROUP BY InwardClearingDate, SendingBank, CheckCount, CheckAmt  
) S JOIN tblRptT001 T ON S.SendingBank = T.SendingBank
GROUP BY S.SendingBank,S.TotalCount,S.TotalAmt,T.InwardClearingDate

Answer 2

我知道我为平均数做了什么是完全错误的，我坚持认为，因为不是每个月都有相同的天数。

要解决这个问题，请考虑在InwardClearingDate上应用DAY和EOMONTH（）函数

SELECT SendingBank, CheckCount As TotalCount, CheckAmt As TotalAmt,
    AVG(CheckCount/DAY(EOMONTH(InwardClearingDate)) AS DaysInMonth) AS AvgDailyCount,   
    AVG(CheckAmt/DAY(EOMONTH(InwardClearingDate)) AS DaysInMonth) AS AvgDailyAmt
FROM tblRptT001 
WHERE InwardClearingDate = @asInwardClearingDt
    GROUP BY InwardClearingDate, SendingBank, ChequeCount, ChequeAmt
    ORDER BY InwardClearingDate

Answer 3

请查看这是否是您要找的，

Declare @asInwardClearingDt Date
Declare @month int = (Datediff(Day,@asInwardClearingDt,Dateadd(Month,1,@asInwardClearingDt)))

Select  SendingBank,
        Sum(CheckCount) As TotalCount,
        Sum(CheckAmt) As TotalAmt,
        Sum(CheckCount)/@month As AvgDailyCount,
        Sum(CheckAmt)/@month As AvgDailyAmt
From    tblRptT001
Where   Datepart(MONTH,InwardClearingDate) = Datepart(MONTH,@asInwardClearingDt)
And     Datepart(MONTH,InwardClearingDate) = Datepart(MONTH,@asInwardClearingDt)
Group By SendingBank
