Question

我正在尝试了解客户销售代表的访问次数。上个月我创建了这个 sql 来让我访问当前的客户，但我需要成为 Apple t 才能获得上个月的总访问次数

declare @FromDate date, @ToDate date
set @FromDate = '11/01/2012'
set @ToDate = '11/30/2012'

SELECT COUNT(VisitTracking.customerID) AS #VISIT
FROM VisitTracking INNER JOIN Customers 
   ON VisitTracking.customerID = Customers.customerID  INNER JOIN Customer_Company 
   ON Customers.customerID = Customer_Company.customerID INNER JOIN Company 
   ON Customer_Company.companyID = Company.companyID
 WHERE VisitTracking.DateVisited  BETWEEN 
          DATEADD(m, datediff(DD, 0, @FromDate)-1, 0)  AND  
          DATEADD(M, datediff(month, 0, @ToDate)-1, 0) 
GO 

 SELECT     COUNT(VisitTracking.customerID) AS #VISIT
    FROM         VisitTracking 
    WHERE VisitTracking.DateVisited  BETWEEN DATEADD(m, datediff(DD, 0, @FromDate)-1, 0)  AND DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@ToDate),0))

Answer 1

嗯，也许你可以使用会话属性，，但是使用它，因为你可以达到它的优势，

就像是：

申请开始--->

Application.add("UserCount",0);

会话开始--->

int UserCount=int.parse(Appplication.get("UserCount").tostring()); 用户计数++；Application.set("UserCount",UserCount);

使用此代码

declare @FromDate date
,@ToDate date
set @FromDate = '11/01/2012'
set @ToDate = '11/30/2012'

SELECT     COUNT(VisitTracking.customerID) AS #VISIT
FROM         VisitTracking 
WHERE VisitTracking.DateVisited  BETWEEN DATEADD(m, datediff(MM, 0, @FromDate)-1, 0)  and  DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@ToDate),0))
